A gasoline engine is at a location where the temperature is measured to be 14.8 °C and produces 300 kW at 5800 rpm while consuming 0.0184 kg/s of fuel. During operation, data shows that its mechanical energy loss is 18 %, the actual volume of air going into each cylinder is 80% (the volumetric efficiency has a negligible variation), and the actual fuel-to-air ratio is 0.065. What were the engine parameters at sea level conditions if the pressure here is 99.3 kPa and the temperature here is 18 0C hotter than that of the elevated condition? Determine at sea-level conditions the Brake Power in kW.

At a particular operating condition, an axial flow compressor has a reaction of 0.6, a flow coefficient of 0.5 and a stage loading, defined as Aho U2 of 0.35. If the flow exit angles for each blade row may be assumed to remain unchanged when the mass flow is throttled, determine the reaction of the stage and the stage loading when the air flow is reduced by 10% at constant blade speed.

In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .

Air is blown into the electronic parts of a computer from one opening by the fan, and air is expelled from another opening. The air blown in is blown continuously (steady-state) at a temperature of 20 ℃ and a pressure of 1 atm. In order to keep the noise level low, the blow-in speed of the air is a maximum of 1.3 m/s. In addition, the temperature of the exhausted air is limited to 32 ℃. While the electronic systems of this computer consume 80 kW of energy, the fan system consumes 18 kW of energy. Calculate the minimum required opening area at the air inlet when heat transfer with the environment, changes in kinetic energy and potential energy are neglected.
