3. A storage tank is connected to a pond (at atmospheric pressure!) by a length of 4" pipe and a gate valve. From previous operating experience, it has been found that when the tank is at a pressure of 3 atm the flow through the pipe is 35 m3/h when the gate valve is fully open. If the pressure in the tank increases to 5 atm, what will be the maximum discharge rate from the tank?

Ali Brandt · Answer 1

V2 = 21m³/h

Explanation:

According to Boyle's law, pressure and flow rate of gas can be calculated from the following equation:

P1V1=P2V2

3 * 35 = 5 * V2

V2 = 21m³/h
