For the system shown in Fig. and analyzed in Problem, assume that the energy loss is proportional to the velocity head in the tubing. Compute the pressure in the tank required to cause a flow of 1000 L/min.

Problem:

In Fig, kerosene at 25°C is flowing at 500 L/min from the lower tank to the upper tank through 2-in Type K copper tubing and a valve. If the pressure above the fluid is 15.0 psig, how much energy loss occurs in the system?
