The pump of a water distribution system is powered by a 15-kW electric motor whose efficiency is 90 percent. The water flow rate
wariber [46]

Answer:

Mechanical power of pump is 74.07%.    

Explanation:

Power of motor = 15 KW

Efficiency of motor= 90%

So the actual power(P) supplied by motor = 0.9 x 15 KW

P=13.5 KW

Water flow rate = 50 L/s

Volume flow rate = 50 L/s

We know that

1000\ L/s=1\ m^3/s

So

Volume\ flow \rate =0.05\ m^3/s

We know that pump is an open system and work input for open system can be calculated as

W=VΔP

ΔP is the pressure difference

V is the volume flow rate

So by putting the values

W=0.05 (300-100)            (here ΔP=300 - 100=200 KPa)

W=10 KW    

So mechanical power of pump

\eta =\dfrac{W}{P}        

\eta =\dfrac{10}{13.5}    

η =0.7407

Mechanical power of pump is 74.07%.

What is the meaning of the measurement met?
san4es73 [151]

Answer: MET(Metabolic equivalent of task) is the measurement technique that is based on the ratio of the energy that is being spend by an individual by any physical activity to the energy spent by individual sitting in quiet position.

This ration has some reference in which is ratio is measured.The energy being measured in the activity time of the person considers his/her relative mass at that time. This relative mass is compared in accordance with the  oxygen amount of 3.5 ml per kg/min that is almost equal to energy of the person in the sitting position.

For the system form of the basic laws, the momentum of a system can change as a result of: a. pressure acting on the system. b.
Ymorist [56]

Answer: F. All the above.

Explanation:

Basically, if an object is moving, it moves with a certain velocity and mass. Momentum of a body is a product of mass and velocity. The sum of momentum of individual bodies is equal to the entire system momentum. For instance, a block v is moving due to an applied force F, with a velocity V and the gravity g. Due to gravity, the weight is mg. Due to gravity, the weight is acting downward. Applied force is acting on the block surface area A.

Pressure = Surface force/Surface area.

Surface force is acting on the surface applied. So, acting pressure = Force applied/area.

Pressure and surface force is acting on the body. Body forces also act on the system. Forces due to gravity is also referred to as body force. As a result of weight of the box, Normal force produced by the rough surface is equal to the Weight. As a result of rough surface, frictional forces are produced which opposes the block to move forward. All the external forces create a net total force due to which the block move with a velocity and acceleration.

In Newton's second law, Ftotal is equal to mass × acceleration.

Therefore, we can conclude that momentum can change as a result of all these forces because mass × acceleration is related to total force and momentum is equal to mass × velocity.

Why doesn’t the servant kill the child oedipus as he was ordered to do
Anni [7]
The Servant does not kill the child Oedipus as he was ordered to do because "He pitied the child" based on the Oedipus Rex story. The servant was ordered to kill the child because of the prophecy that predicted King Laius' death. The king already had attempted to hurt Oedipus by piercing Oedipus's ankle. However, the servant did not finish the job and he rather saved the baby Oedipus.
