Your company produces small power units that generate electrical energy by expanding the residual process steam in your turbine. You are asked to study the turbine to determine if it is operating as efficiently as possible. One way to ensure good efficiency is to have the turbine operating adiabatically. Gauge shows that for steam 250 degrees and 20 bar: -The working freckle is 86.5 hp -The steam consumpvtion rate is 1000 lbm/h -The steam leaves the turbine saturated at 1 bar Is the turbine operating adiabatically? Base your answers on calculations.
(b) A heat engine with a thermal efficiency of 40 percent rejects 1000 kJ/kg of heat. Determine the amount of heat it receives.
The power required to drive the compressor in a Carnot refrigerator is 62 hp. It operates between -6°C and 45°C. Determine the coefficient of performance. Final answer must be in 3 decimal places.
An engineer receives a schematic fora reversible heat engine with three reservoirs at the temperatures shown to the right. The heat engine produces 1800 kW work as it pulls 3200 kW of heat from the 600K reservoir. The engineer wonders if the schematic is drawn correctly (in other words, are the arrows going the correct directions?) To answer this question, (a) calculate the heat interactions of the HE with the other two reservoirs. (b)If necessary, draw an updated diagram with the correct directionalities indicating the rates of heat transfer.
You are purchasing a refrigerator. You know that you want to keep your food at 1 deg C and that your house is typically at 19 deg C. What is the minimum power (kW) required to operate the refrigerator if the heat extracted is 297 kW?
