3. A desktop computer is to be cooled by a fan whose flow rate is 0.34 m/min. Determine the mass flow rate of air, in kg/s, through the fan at an elevation of 3400 m where the air density is 0.7 kg/m³. Also, if the average velocity of air is not to exceed 110 m/min, find the diameter of the casing of the fan, in mm.
Q/ Super-heated vapor enters condenser of a steam power plant at 2 bar and 250 °C. The vapor is condensed at 0.2 bar and 60 °C. Condensed cooling water enters into another streamline at 25 °C and the water exits at 40 °C. The heat is transferred from the condensing steam to the cooling water with no change in kinetic and potential energies. Calculate (a) the ratio of the cooling water mass flow rate to the condensing steam mass flow rate. (b) The specific heat transfer from the condensing steam to the cooling water.

A turbine, operating under steady-flow conditions, receives X1 kg of steam per hour (For X1 refer Table. 1). The steam enters the turbine at a velocity of 3000 m/min, an elevation of 5 m and a specific enthalpy of 2787 kJ/kg. It leaves the turbine at a velocity of 6000 m/min, an elevation of 1 m and a specific enthalpy of 2259 kJ/kg. Heat losses from the turbine to the surroundings amount to 16736 kJ/h. Determine the power output of the turbine.
