Two water reservoirs A and B are connected through a 40-m long, 2-cm diameter cast iron pipe with a sharp-edged entrance. The pipe also involves a swing check valve and a fully open gate valve. The water level in both reservoirs is the same, but reservoir A is pressurized by compressed air while reservoir B is open to the atmosphere at 88 kPa. The water temperature is 10°C. a. If the initial flow rate through the pipe is 1.2 L/s, determine the absolute air pressure on top of reservoir A.

Question
Two water reservoirs A and B are connected through a 40-m long, 2-cm diameter cast iron pipe with a sharp-edged entrance. The pipe also involves a swing check valve and a fully open gate valve. The water level in both reservoirs is the same, but reservoir A is pressurized by compressed air while reservoir B is open to the atmosphere at 88 kPa. The water temperature is 10°C. a. If the initial flow rate through the pipe is 1.2 L/s, determine the absolute air pressure on top of reservoir A. b. Determine the pressure just before the valve
