Question 5: Water enters a hydraulic turbine through a $$30?\mathrm{cm}$$ diameter pipe at a rate of $$0.6{\mathrm{m}}^3/\mathrm{s}$$ and exits through a $$25?\mathrm{cm}$$ diameter pipe. The pressure drop in the turbine is measured to be $$148\mathrm{kPa}$$. For a combined turbine-generator efficiency of 83 percent, determine the net electric power output. Disregard the effect of the kinetic energy correction factors. Assumptions 1 The flow is steady and incompressible. 2 All losses in the turbine are accounted for by turbine efficiency and thus $$h_1=0.3$$ The elevation difference across the turbine is negligible. 4 The effect of the kinetic energy correction factors is negligible, $${?}_1={?}_2=?=1$$.
