Z≤ -4.852 ft, Maximum efficiency is η≅ 0.88 ≅ 88% is the maximum discharge possible

Solution

Given Data:-

D = 14.62in, N = 2134 rc/min, T=20°C. At T= 20°C ɣ=ρg= 62.35 lb/ft³, vapor pressure. Pv = 49.2 lb/ft².

The efficienies at each flow rate is computal by using formula

η = ρgθH / (550) (bhp)

→ As we can See the maximum efficiency point is at θ = 6ft³/s (close to 6ft³/s)

Maximum efficiency is η≅ 0.88 ≅ 88%

b) Given NPSHR = 16 ft,hg=22ft. Zactual. = 9ft (below the sea surface)

To avoid cavitation NPSH < Pa - Pv/ρg - Z - hf

Z < Pa - Pv/ρg - hf

Z < 2116 - 49.2/62.35 - 16 - 22 [1 atm = 2116 lb/ft2]

Z≤ -4.852 ft

-> Keeping the pump 9 ft below the surface gives 4.148 ft of marign against cavitation.

Answer:

the angular acceleration of each drum depends on the applied force F. If the force is known, then the angular acceleration can be calculated. If the force is not known, then the angular acceleration cannot be calculated.

Explanation:

To find the angular acceleration of each drum, we can use the equation for rotational dynamics:

[tex]I * alpha = F * r[/tex]

where I is the moment of inertia of the drum, alpha is the angular acceleration, F is the applied force, and r is the distance from the center of rotation to the point where the force is applied.

In this case, the moment of inertia of each drum is given by:

[tex]I = mr^2[/tex]

where m is the mass of the drum and r is the radius of gyration. Substituting this expression into the equation above, we get:

[tex](m * r^2) * alpha = F * r[/tex]

Solving for alpha, we find that:

[tex]alpha = F * r / (m * r^2)[/tex]

Substituting the given values, we find that the angular acceleration of each drum is:

[tex]alpha = F * 250 mm / (105 kg * (370 mm)^2)[/tex]

This equation can be simplified to:

[tex]alpha = F / (7.29 * 105 kg)[/tex]

So the angular acceleration of each drum depends on the applied force F. If the force is known, then the angular acceleration can be calculated. If the force is not known, then the angular acceleration cannot be calculated.

The ability of a differential amplifier (or other device) to reject common-mode signals is measured using the common mode rejection ratio (CMRR). The CMRR of a differential amplifier should be infinite, however this is not practical. The non-inverting amplifier has a positive gain while the inverting amplifier has a negative gain.

How much gain does an inverting versus a non-inverting amplifier have?

The ratio of the resistances determines the gain that the inverting amplifier offers. Contrarily, the non-inverting amplifier's gain is calculated by adding 1 to the resistances' respective ratios.

What is the ratio of cm gain to non-inverting gain?

Remember that non-inverting gain is 1+k while inverting voltage gain has the ratio =-k. For a given R ratio, k=R2/R1, therefore A v (C M) = (R 2 R 1 + 1) (R 2 ′ R 1 ′ + R 2 ′) (R 2 R 1) = 0 for a given CM gain to a certain bias current DC offset voltage.

It is not plausible that hatchability is independent of exposure time.

To perform a chi-squared take a look at to determine whether or not it's miles achievable that the eclosion fee does now no longer rely upon publicity length, the correct hypotheses might be:

H0:

pij = pi · pj (the eclosion fee is impartial of publicity length)

Ha:

as a minimum one pij ≠ pi · pj (the eclosion fee isn't always impartial of publicity length)

To compute the take a look at statistic fee, we want to first calculate the predicted wide variety of bugs that could emerge for every length. We can try this with the aid of using multiplying the row overall with the aid of using the column overall and dividing with the aid of using the full wide variety of bugs:

Expected matter for length 0, pattern length 125:

125106÷300 = 52.five

Expected matter for length 1, pattern length 41:

4138÷300 = 16.2

Expected matter for length 2, pattern length 47:

4744÷300 = 19.6

Expected matter for length three, pattern length 44:

4440÷300 = 18.four

Expected matter for length five, pattern length 46:

4638÷300 = 18.four

Expected matter for length 10, pattern length 42:

4235÷300 = 17.1

Expected matter for length 15, pattern length 10:

10×7÷300 = 0.7

Then we will calculate the chi-squared statistic the use of the subsequent formula:

χ2 = ∑(Oi - Ei)∧2 / Ei

in which Oi is the located matter and Ei is the predicted matter.

Plugging withinside the values, we get:

χ2 = (106 - 52.5)^2÷52.five + (38 - 16.2)^2/16.2 + (44 - 19.6)^2÷19.6 + (40 - 18.four)^2÷18.four + (38 - 18.four)^2÷18.four + (35 - 17.1)^2/17.1 + (7 - 0.7)^2÷0.7 = 71.4

To decide the P-fee, we want to appearance up the fee of χ2 in a chi-squared distribution desk with 6 stages of freedom (due to the fact that there are three rows and seven columns, and we're treating the row and column totals as fixed). From the desk, we will see that the P-fee is much less than 0.005.

To find the damping constant c, we need to consider both the overshoot and rise time specifications.

We determine the natural frequency ωn of the system. The natural frequency is related to the damping constant c and the undamped natural frequency wn0 by

ωn = ωn0 × √(1 - c^2)

From the graph provided, we can see that the maximum percentage overrun is 20%. This means that the response of the system to a step input oscillates around steady state with an amplitude of 20% of steady state. You can find ωn using the percent overshoot formula for a second-order system.

% overshoot = e^(-c × ωn × π ÷ √(1-c^2))

Solving this equation for ωn gives us:

ωn = -ln(20%) / (c × π / √(1-c^2))

(a) The natural frequency of the system is ωn = -ln(20%) ÷ (c × π / √(1-c^2)).

(b) Because of the overshoot specification, the range of c is c >= -ln(20%) ÷ (ωn × π ÷ √(1-c^2)).

(c) Because of the rise time specification, the restrictions on c are c <= 3 × √(1 - c^2) ÷ π and ωn >= 3 ÷ π.

(d) The damping constant c is the intersection of the range determined by the overshoot specification and the constraint determined by the rise time specification. Both specifications are not met because the range specified by the overshoot specification is larger than the limit specified by the rise time specification.

Another approach is to iterate over the string and keep track of the characters that have already been seen. If a character is seen for the first time, we can store it in a variable and return it. If all characters have been seen more than once, we can return '_'.

A third approach is to use a stack. For each character in the string, we can push it to the stack. If the character is already on the stack, we can pop it off. If the stack is empty at the end, we can return '_'. Otherwise, we can return the character at the top of the stack.

A DSS is a computer-based system that uses data, models, and other tools to help decision makers make better decisions. It is typically used in situations where there is a need to analyze large amounts of data, evaluate complex situations, and make decisions in real time.

One of the tools used to support the decision making process in a DSS is a data analysis tool, which converts raw data into meaningful information. This type of tool typically uses algorithms, statistical techniques, and other methods to process and analyze data, and produces reports, charts, and other visualizations that can help decision makers understand the data and make informed decisions.

The stage of information systems that converts raw data into a meaningful form is called data processing. This stage involves transforming raw data into a format that is usable and understandable, typically by using algorithms, software, and other tools.

In summary, the function of an information system that converts raw input into a meaningful form is data processing, which is a stage in the information system lifecycle that is essential for decision making.
