Consider a wind turbine that is situated in an area that has steady winds. The turbine rotates at 16 RPM. The mass flow rate through the turbine is 41,025 kg/s. The tip velocity is 260 km/hr. Take the air density to be 1.31 kg/m² and assume 180kW of electric power is generated by the turbine. Determine the following: a. Average velocity of the air b. The efficiency of the turbine c. Assuming winds are steady for 95% of the year, is this a suitable location for a wind turbine? Explain.
The compressor (10 hp) pulls in gas at 150 psi and 10.5 ft3/lbm velocity at the entrance is 2 ft/s, exhausts the gas at 900 psi and 0.0541 ft³/lbm, velocity at the exit is 55 ft/s. Heat is lost at a rate of 60 BTU/s. Determine the mass flow rate of the air (Ibm/s).
Disregard the velocity at the entrance
A site is being considered for wind power generation. At this site, the wind blows steadily at 9 m/s for 2,579 hours per year. Assuming the wind velocity is negligible at other times for simplicity, determine the kWh/year that can be produced at the site for a turbine with a mechanical efficiency of 100% and an effective flow area of 5 m2. Use a value of 1.25 kg/m3 for the density of the air. Give your answer in killowatt-hours per year (kWh/year). Hint: I reccomend starting by finding the kinetic energy (kJ/kg) of the wind. Hint 2: Multiply the power generation (kW) by the number of hours of wind per year (h/year) to get kWh/year.
A 5 KW pump is used to raise the elevation of a lake's water by 25 m from the free surface of the lake. The pipe inlet is 2 m below the free surface. The temperature of water increases by 0.05oC during the process as a result of the frictional effects. Neglecting any heat transfer and kinetic energy changes, determine the mass flow rate of the water.

The valve connected to a 450-liter insulated tank of air at 250 kPa and 50̊C is opened,allowing the gas to escape until its pressure drops to 120 kPa. An electric heater insidethe tank maintains the temperature at 50̊C. Using variable specific heats, Determine thefollowing:a) The mass of air withdrawn (kg)b) The energy input to the resistor (kJ)
A man purchases a turbine for use in his factory. He sets it up so that there is steam entering at 5000 kpa and at 873.15 Kelvin at a constant rate of 100 m/sec. This steam seems to leave the turbine at 100 m/sec and of 95% quality at a pressure of 0.01MPa. The manufacturer sticker claims the turbine has a power output known to be 56400 Joules per second. Find the theoretical mass flowrate of the steam through the device [kg/sec] and the area of the outlet [m^2]
A pump increases the water presssure from 8kPa at the inlet to 700 kPa at the outlet.
