A 70 percent efficient pump delivers water at 20 C from one reservoir to another 20 ft higher. The piping system consistsof 60 ft of galvanized iron pipe with a 2 in diameter, a reentrant entrance, two screwed 90-degree long-radius elbows, ascrewed-open gate valve, and a sharp exit. What is the input power required in horsepower with and without a 6-degreewell-designed conical expansion added to the exit

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.

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.
