6. A working area of a mine has diesel equipment operating within it. The maximum diesel loading is 750 kW. The same section of the mine also has a methane inflow of 0.25 m³/s flowing into it. If the maximum permissible methane concentration in the general body of the air is 0.5% and the design diesel air quantity is 5 m³/s per 100 kW of installed diesel power, determine the required ventilation flow rate for the working area.

The moist air at 30 C° and 50 % RH enters steady state dehumidifier at the rate of 280 m³/min. The air passes over a cooling coil and water vapour condenses. The saturated moist air exists at 10 C°. The condensate also leaves the dehumidifier at 10 C°. The pressure is atmospheric. Determine 1- The mass flow rate of dry air. 2- The rate at which water is condensed. 3- The required refrigerating capacity in ton of refrigeration.
This question requires the use of the extracts from the tables of thermodynamic properties supplied. Ammonia, NH3, was once a commonly used refrigerant. In a particular (very old) refrigeration plant, ammonia has a pressure of 1.9 bar and a temperature of 30 °C. What would be the specific entropy of the ammonia under these conditions. а. 6.04 kJ/kg K O b. 6.38 kJ/kg K С. 6.20 kJ/kg K d. 5.62 kJ/kg K е. 0.37 kJ/kg K
During the compression stroke of a certain gasoline engine, the pressure increases from 1.00 atm to 19.0 atm. The process is adiabatic and the air-fuel mixture behaves as a diatomic ideal gas. (a) By what factor does the volume change? Vfinal = Vinitial (b) By what factor does the temperature change? Tinal = Tinitial Assume the compression starts with 0.016 mole of gas at 28.5°C. (c) Find the value of Q that characterizes the process. (d) Find the value of AEnt that characterizes the process. (e) Find the value of W that characterizes the process.
