- Which of the following represents the specific volume of the steam during its phase transition? Let x = dryness fraction, y = moisture content, j = specific volume at saturated liquid condition, and k = specific volume at saturated vapor condition.In the engine of a car that uses petrol as fuel, when the piston is at its highest position, air at 10 bar and 100°C enters the cylinder. Without any change in the volume, ignition occurs, and the air temperature rises to 1500°C. What is the air pressure after the ignition? (Select the closest value)[Whenever necessary, assume air as an ideal gas and consider R = 287 J/(kg.K).]Enthalpy of vaporisation is equal to __________at critical point. A. saturation temperature B. zero C. saturation point D. saturation pressure
- Request: Can you please help me with answering the following question? Thank you for all your hard work here and only do what you can. Question: When a compressed gas storage tank fails, the resultant explosion occurs so rapidly that the gas cloud can be considered adiabatic and assumed to not mix appreciably with the surrounding atmosphere. Consider the failure of a 2.5-m3 air storage tank initially at 15 bar. Atmospheric pressure is 1 bar, Cp = 7R/2. Provide an estimate by assuming reversibility. (a) Calculate the work done on the atmosphere. Does the reversibility approximation over-estimate or under-estimate the actual work? (b) A detonation of 1 kg of TNT releases about 4.5 MJ of work. Calculate the equivalent mass of TNT that performs the same work as in part (a).What is the advantage of having high steam quality compare to low steam quality?- A combined gas turbine–vapor power plant operates as in Fig. Steady-state data at principal states of the combined cycle are given in the table below. An air-standard analysis is assumed for the gas turbine in which the air passing through the combustor receives energy by heat transfer at a rate of 50 MW. Except for the combustor, all components operate adiabatically. Kinetic and potential energy effects are negligible. Determine (a) the mass flow rates of the air, steam, and cooling water, each in kg/s, (b) the net power developed by the gas turbine cycle and the vapor cycle, respectively, each in MW, (c) the thermal efficiency of the combined cycle.
