Water is flowing at the rate of 1.676 m/s in a 3.068 inches’ diameter horizontal pipe at a pressure p1 of 68.9 kPa. It then passes to a pipe having an inside diameter of 2.067 inch. The density of the water is 998 kg/m3 . a) Calculate the new pressure p2 in the 2.067inch pipe. Assume no friction losses b) If the piping is vertical and the flow is upward, calculate the new pressure p2. The pressure tap for p2 is 0.457 m above the tap for p1. c) Compare and discuss your answers in 2 (a) and 2(b). answer b and c

Answer #1

C) dueto pipe orientation from horizontal to vertical an potential energy components is added in the energy equation(Bernoulli equations).this the main reason to decrease pressure at 2 when pipe is at vertical .

P2 =59.024 KPa (vertical)

P2 =63.498 KPa( horizontal)
