Diameter of the horizontal pipe = 1.5m Flow rate = 8-meter cube per second The length of length of reservoir= 10 meters The valve that is located 10 km closed at t=0 and take 10 seconds for complete closed Bulk modulus of electricity of water = Ev= 2.2 GPa a. Estimate the pressure inside pipe due to water hammer

According to the given formula we can easily find the value of estimated pressure

a. Energy lost is almost zero plot the pressure distribution, the direction of water flow, direction of pressure wave along the pipe at t =15 

Plot pressure distribution

The direction of water flow

Direction of pressure wave along the pipe at t =15
