972) MULTI-STEP PROBLEM B A concrete pumper truck can conveniently deliver wet concrete onto a construction site with minimal manual tabor. The 100 kW pump (actual power input) delivers an approximately steady-state- steady-flow (SSSF) of 120 kg/s of wet concrete. The fluid flows through a 60 m long hose from the concrete pump exit at (1) to the hose exit into the atmosphere at (2). Frictional dissipation of mechanical work in the hose from (1) → (2) is 80 J/kg. Given Pluid density = 2300 kg/m Use dimensions shown. The average bulk flow velocity at the hose exit is vi- 4.24_(m/s) The static pressure at the hose Inlet is p = SIZ. (Pa. gauge)
