Question
A large water tank (rho_w = 62.4 lb_m/ft^3) has two inlets and a single outlet. Inlet 1 is constructed of 2" Sch 40 pipe with a 15 degree diffuser and has a mass flow rate and pressure of 12.5 lbm/s and 50 psi respectively. Inlet 2 is a sharp edged 4" Sch 40 pipe with a mass flow rate and pressure of 35 lbm/s and 42.3 psi respectively. The elevation difference between the 2 inlets is Delta z_2 = 20 ft. Exit 3 is deltaz_3 = 50 ft higher than inlet 1 and consists of a 3" Sch 40 re-entrant pipe. Determine the exit velocity and pressure.Explanation / Answer
