A horizontal shaft centrifugal pump lifts ware at 65°C. The suction nozzle is one meter below pump centerline. The pressure at this point equal $$200$$ $$kPa$$ gauge and velocity is $$3$$ $$m/s.$$ Steam tables show saturation pressure at $${65^0}C$$ is $$25$$ $$kPa,$$ and specific volume of the saturated liquid is $$0.001020$$$ $${m^3}/kg.$$ . The pump Net Positive suction Head ($$NPSH$$) in meters is

A large hydraulic turbine is to generate $$300$$ $$kW$$ at $$1000$$ $$rpm$$ under a head of $$40$$ $$m$$. for initial testing, a $$1:4$$ scale model of the turbine operates under a head of $$10$$ $$m.$$ the power generated by the model (in $$kW$$) will be

In a Pelton wheel, the bucket peripheral speed is $$10$$ $$m/s,$$ the water jet velocity is $$25$$ $$m/s$$ and volumetric flow rate of the jet is $$0.1{m^3}/s.$$ If the jet deflection angle is $${120^0}$$ and the flow is ideal, the owe developed is:
