You are designing a piping system. At one point in this system there is a contraction from a 4-in Schedule 80 pipe to a 1.5-in Schedule 80 pipe. The flow rate is x gallons/minute. Please calculate the energy loss for the following cases. The details are given below. x (gal/min) = y (degree) = 110.20 76 = 1) A sudden contraction 2) A gradual contraction with a cone angle of y degrees
