Chapter 5, Problem 5.10E

Air is used as a working substance in a given internal combustion engine, which is supplied with heat at a constant volume. Based on the data, calculate the The work of the cycle.

In a steady flow process, the working fluid flows at a rate of 240 kg/min. The fluid rejects 120 kJ/s passing through the system. The conditions of fluid at inlet and outlet are given as : C1 = 300 m/s, p1 = 6.2 bar,u1 = 2100 kJ/kg, v1 = 0.37 m3/kg and C2 = 150 m/s, p2 = 1.3 bar, u2 = 1500 kJ/kg, v2 = 1.2 m3/kg. The suffix 1 indicates the conditions at inlet and 2 indicates at outlet of the system. Neglecting the change in potential energy, determine the power capacity of the system in MW.

why radial gas turbines and compressors are not suitable for large applications.

If i see any mistake i will dislike and Report. So don't waste time by submitting Wrong Answer.

Please provide complete solution with units of measurement.

Explain the causes of Irreversibility. Thermodynamics subject. -viscous flow of a fluid -fluif flow through valves and porous plugs (throttling)

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.

Air is used as a working substance in a given internal combustion engine, which is supplied with heat at a constant volume. Based on the data, calculate the The average pressure of the cycle.

QI/ An open belt running over two pulleys 24 cm and 60 cm diameters connects two parallel shafts 3 m apart and transmits 3.75 KW from the smaller pulley that rotates at 300 r.p.m. coefficient of friction between the belt and the pulleys is 0.3 and the safe working tension is 100 N/cm width. Determine: i) minimum width of the belt, ii) initial belt tension, and iii) length of the belt required.
