Apump draws water from a storage tank (water surface elevation = 70 ft) through a 6-inh pipe. the pump is at an elevation of 50 ft and its 4-inch diameter delivery pipe terminates at a 3 inch diameter nozzle at an elevation of 80 ft. head losses amount to 5 v^2/2g in the 6 inch pipe and 12 v^2 /2g in the 4 inch pipe. if the pump develops a head of 80 ft, what is the system discharge?

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
