A 90 deg V-notch and a rectangular weir are placed in series. The length of the rectangular weir is 0.6 m and its coefficient is 1.81. If the coefficient of contraction of the V-notch is 0.61, what will be the working head when the head on the weir is 0.15 m?

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.
