Select all of the air-standard assumptions   Question 1 options:   The working fluid is air, which operates in a closed loop and is an ideal gas.   The working fluid is air, which operates in a closed loop and is not an ideal gas.   All processes in the cycle are internally reversible.   All processes in the cycle are isentropic.   The exhaust is expelled into the surrounding atmosphere.   The exhaust is replaced by a heat-rejection process.   The combustion process involves the addition of fuel into air.   The combustion process is replaced by a heat-addition process.   Approximate analysis   Exact analysis   Specific heats are constant and evaluated at 25C

B-Correct the wrong sentence: 1. Adiabatic compression is the most desirable process to get minimum work in the compressor. 2. The thermal efficiency of constant pressure cycle is depends on the compression ratio 3. The most important fuel elements are carbon and ash. 4. The pressure of a mixture of gases is equal to the sum of partial masses of the constituents. 5. The Rankine cycle is the most efficient cycle

Which statement/s are true? Heat is transferred to a system by either an air-sourced Carnot heat pump, an electrical resistance heater or a heat source at temperature marginally higher than the system temperature. The loss of Carnot Work Potential (Exergy destruction, or T0Sloss term) is minimum when heat is added by the air-sourced Carnot heat pump.   Heat is transferred to a system either by an 100% efficient electrical resistance heater, or an 100% efficient isothermal heat source. The loss of Carnot Work Potential (Exergy destruction, or T0Sloss term) is zero when heat is added by the isothermal heat source.   Heat is transferred to a system by either an air-sourced Carnot heat pump, an electrical resistance heater, or a heat source at temperature marginally higher than the system temperature. The loss of Carnot Work Potential (Exergy destruction, or T0Sloss term) is maximum when heat is added by the electric resistance heater.   Heat is transferred to a system by either a…

Steam enters the turbine of a vapor power plant at 600 lbf/in.2, 1000°F and exits as a two-phase liquid–vapor mixture at 90°F. Condensate exits the condenser at 85°F and is pumped to 600 lbf/in.2 The turbine and pump isentropic efficiencies are 90 and 80%, respectively. The net power developed is 1 MW.Determine:(a) the percent steam quality at the turbine exit.(b) the percent thermal efficiency.(c) the steam mass flow rate, in lb/h.
