1. The hydraulic efficiency of an impulse turbine is the ?ratio of the actual power produced by the turbine to the energy actually supplied by the turbine ratio of the actual work available at the turbine to the energy imparted to the wheel ratio of the work done on the wheel to the energy of the jet none of the above

A 5 cm diameter jet of water having a velocity of20 m/s impinges normally on a flat vertical platethat is moving away from the jet with a velocityof 8 m/s. Efficiency of power transmission by jetimpingement is _______ (in percentage) (correctupto two decimal places

What is Mechanical Efficiency?The ratio of the power output of the pump to the power input to the pumpThe ratio of the power available at the impeller to the power at the shaft of the centrifugal pumpThe ratio of the power delivered to the water at the pump's outlet to the power available at the impellerNone of the above

In an inward flow reaction turbine, the diameter of the outer periphery is twice the diameter of the inner one, and the turbine operates under a head of 20 m. The turbine has radial tis at the outlet while at the exit blades make an angle of 30° with the forward tangent. Assuming a constant radial velocity of flow and that the blade friction accounts for a dissipation of energy equivalent to 10 percent of kinetic energy at the outlet, find (i) runner velocity at the rim, (ii) hydraulic efficiency of the turbine. Assume radial discharge at outlet.

A gas turbine power plant generates electricity by burning natural gas and using the resulting hot gases to drive a turbine. Which law of thermodynamics is relevant to the efficiency of this power generation process?*First law of thermodynamicsSecond law of thermodynamicsThird law of thermodynamicsZeroth law of thermodynamics
