A horizontal pipe with a diameter of 4 inches abruptly connects to a larger pipe of 12 inches in diameter in an industrial application.

The flow is turbulent and the volume flow rate is 10 ft3/s in the smaller pipe and its pressure is 75 psia. The water temperature is 70-degrees Fahrenheit and the kinetic energy correction factor is 1.06 for the inlet and outlet connection.
What is the loss coefficient, KL
What is the head loss in feet
What is the pressure in the larger pipe downstream from the transition in psia
