During the test of a Pelton wheel, the pressure at the end of the 6.10" diameter nozzle was 515 psig when the flow is 2,615 ft/min. The peripheral coefficient is 0.46, the turbine specific speed is 6.20 rpm, and the penstock diameter is 1.5 feet. If the mechanical efficiency is 86% and electrical efficiency is 85%, determine the diameter of wheel in feet.
a constant pressure container (inside the piston-cylinder) with 250 kPa pressureat the beginning the mass of the saturated water vapor was 8 kg. Then the saturated steam in the cylinder compressed to 3/4 of its mass vy cooling.1) what's the amount of heat transferred to the environment.
A steam turbine is to operate on a simple regenerative cycle. Steam is supplied dry saturated at 40 bar, and is exhausted to a condenser at 0.07 bar. The condensate is pumped to a pressure of 3.5 bar at which it is mixed with bleed steam from the turbine at 3.5 bar. The resulting water which is at saturation temperature is then pumped to the boiler. For the ideal cycle sketch the process on the T-s diagram and calculate, neglecting feed pump work,The amount of bleed steam required per kg of supply steamThe thermal efficiency of the plantThe specific steam consumption

One single phase energy meter operating on 230 V and 5 A for 5 hours makes 1940 revolutions. Meter constant in revolution is 400. The power factor of the load will be:
Steam at a pressure of 0.08 bar and a quality of 99.0% enters a shell-and-tube heat exchanger where it condenses on the outside of tubes through which cooling water flows, exiting as saturated liquid at 0.08 bar. The mass flow rate of the condensing steam is 5.8 x 105 kg/h. Cooling water enters the tubes at 15°C and exits at 35°C with negligible change in pressure. Neglecting stray heat transfer and ignoring kinetic and potential energy effects, determine the mass flow rate of the cooling water, in kg/h, for steady-state operation. mwater = i 568765.92 kg/h
An insulated piston-cylinder device contains 4 L of saturated liquid water at a constant pressure of 200 kPa. Water is stirred by a paddle wheel while a current of 8A flows for 50 min through a resistor placed in the water. If one-half of the liquid is evaporated during this constant-pressure process and the paddle-wheel work amounts to 300 kJ, determine the voltage of the source. Also, show the process on a P-v diagram with respect to the saturation lines.
