An open tank contain oil of specific gravity 0.75 on top of
water. If the depth of oil is 2m and the depth of water is 3m.
calculate the gauge and absolute pressures at the bottom of the
tank when the atmospheric pressure is 1bar

Answers

Answer 1

Let's not take into account atmospheric pressure.

Pressure P = Pressure of oil column + Pressure of water column

= h1 . d1.g + h2.d2. g

=( 0.5 x 800 x 9.8) + ( 1x 1000x 9.8) = 3920+ 9800 = 13720

Hence guage pressure at bottom is

P= 13720 N/ m^2

Six 20 watt, 12-volt luminaires (lighting fixtures) are supplied from a small, 12-volt transformer that is 60 feet away from the fixtures. the wire used is 14 awg. what is the voltage applied to the fixtures? use k = 11.6.

Answers

If the wire used is 14 awg. The voltage applied to the fixtures is: 8.61 volts.

Voltage applied to the fixtures

First step is to calculate the amperes using this formula

I = P ÷ E

Where:

I =load current (amperes)=?

P =Product of voltage=(6)(20)

E =Electrical circuit's=12

Let plug in the formula

I= (6)(20) ÷ 12

I=120÷12

I= 10 amps

Second step is to calculate the Voltage drop

Using this formula

Vd = [2KIL] ÷ CMA

Where:

Vd= Voltage drop( volts)=?

K=Direct current constant=11.6

I=Load current (amperes)= 10 amps

L =Length in feet=60 feet

CMA=Circular mill area= 4110

Let plug in the formula

Vd= [(2)(11.6)(10)(60)] ÷ 4110

Vd=13,920÷4110

Vd= 3.3869 volts

Third step is to calculate Voltage at fixture

Voltage at fixtures=Electrical circuit's-Voltage drop

Voltage at fixtures=12 - 3.3869

Voltage at fixtures=8.6131 volts

Voltage at fixtures=8.61 volts (Approximately)

Therefore the voltage applied to the fixtures is: 8.61 volts.

Answers

The number of trays that should be prepared if the owner wants a service level of at least 95% is; 7 trays

How to utilize z-score statistics?

We are given;

Mean; μ = 15

Standard Deviation; σ = 5

We are told that the distribution of demand score is a bell shaped distribution that is a normal distribution.

Formula for z-score is;

z = (x' - μ)/σ

We want to find the value of x such that the probability is 0.95;

P(X > x) = P(z > (x - 15)/5) = 0.95

⇒ 1 -  P(z ≤ (x - 15)/5) = 0.95

Thus;

P(z ≤ (x - 15)/5) = 1 - 0.95

P(z ≤ (x - 15)/5) = 0.05

The value of z from the z-table of 0.05 is -1.645

(x - 15)/5 = -1.645

Answers

Answer:

C) recovers refrigerant in a non-pressurized container

The system dependent (passive) recovery process recovers refrigerant in a non-pressurized container. The correct option is C.

A way of recovering refrigerant from a system without using a pump or heat is known as a system-dependent (passive) recovery process.

Instead, it relies on the system's normal pressure and temperature variations to speed up the recovery process.

A non-pressurized container is commonly connected to the system using this technique, and the refrigerant is then passively allowed to flow inside the container.

The system-dependent recovery procedure, according to Option C, recovers refrigerant in a non-pressurized container.

It entails that the refrigerant is gathered in a container without the need of a pump or additional pressure.
