Problem 77P
The water level in a tank is 20 m above the ground. A hose is connected to the bottom of the tank, and the nozzle at the end of the hose is pointed straight up. The tank is at sea level, and the water surface is open to the atmosphere. In the line leading from the tank to the nozzle is a pump, which increases the pressure of water. If the water jet rises to a
height of 27 m from the ground, determine the minimum pressure rise supplied by the pump to the water line.

Problem 77P
The water level in a tank is 20 m above the ground. A hose is connected to the bottom of the tank, and the nozzle at the end of the hose is pointed straight up. The tank is at sea level, and the water surface is open to the atmosphere. In the line leading from the tank to the nozzle is a pump, which increases the pressure of water. If the water jet rises to a
height of 27 m from the ground, determine the minimum pressure rise supplied by the pump to the water line.
ANSWER:
Solution 77P
We need to calculate the minimum pressure rise supplied by the pump to the water line.
Step 1
The water surface in the tank is open to the atmosphere.
Similarly, the water that rises through the hose is also exposed to the atmosphere.
So, these two different water levels are exposed to same atmospheric pressure.
