1. A truck with heaped capacity of 10 cy is used to disposed to excavated material at dumpsite of 5 miles from the job site. The average velocity of the is 30 mph. The dump time is 30 second and load time is 50 second. Determine the production capacity of the dump truck.

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.
