can you please solve this for me, thanks. 10 kg/s of steam (H2O) enters a turbine at 10 m/s and a specific enthalpy of 3500 kJ/kg and leaves at an outlet 10m below the inlet with a specific enthalpy of 2500 kJ/kg and a velocity of 20 m/s. Assume steady-state steady-flow. If the heat lost from the turbine is 20% that of the turbine work, determine a.) the turbine horsepower. If the turbine is coupled to a generator with a 90% electrical efficiency, and the turbine horsepower has an 80% mechanical efficiency, b.) how much income will a power plant generate in one year if the electrical energy is sold at PhP 3.51 per kW-hr? (Hint: Mechanical efficiency = actual turbine work / ideal turbine work. Electrical efficiency of a generator = electrical output / actual turbine work.)

A turbine operating under steady-flow condition receives steam at the following state: pressure,13.8bar; specific volume 0143 m3 /kg, and velocity 30m/s. The state of the steam leaving the turbine is as follow: pressure 0.35 bar, specific volume 4.37 m3/kg and velocity 90 m/s. The difference in elevation is negligible. Heat is rejected to the surrounding at the rate of 0.25 kW, the turbine develops 103kW of power and the rate of steam flow through the turbine is 0.5 kg/s.

Steam enters an adiabatic turbine at the rate of 50 kg/sec. If the steam properties at the inlet are the following: enthalpy = 3520 KJ/kg and velocity = 10 m/sec, at the outlet which is 5 m below the turbine inlet, enthalpy = 2250 kJ/kg and velocity = 275 m/sec, the change in potential energy in kW is nearly equal to?
Box the final answer. Write legibly. Steam flows into a turbine at a rate of 3.5 kg/s and ¾ MW of heat are lost from the turbine. Ignoring elevation and kinetic energy effects, calculate the power output from the turbine in KW? Steam pressure entering the turbine is 62 Bar at 440ºC and leaves at 74 Kpa.

A boiler takes in feed water at 70 °C and generates steam at a pressure of 10 bar and drynessfraction 0.92. The wet steam enters a superheater and emerges with the same pressure at atemperature of 400 °C. If the steam flow rate is 5 tonnes per hour, determine (i) the rate atwhich heat transfer takes place in the boiler and (ii) the rate at which heat transfer takes placein the superheater. State any assumptions you have made in relation to the steady flowequation for the process.
