For the following questions answer them individually
What is the other name for Diesel Cycle?
If a Carnot engine rejects ¼ of the heat from the reservoir, what is the efficiency of Carnot engine?
One kg of air (R=287 J/kg-K) goes through an irreversible process between two equilibrium state 1 ($$30^\circ C$$, 1.2 m$$^3$$) and state 2 ($$30^\circ C$$, 0.8 m$$^3$$). What is the change in entropy (in J/kg-K)?
A Carnot engine operates between temperature 1000 K and 400 K. The heat rejected by the first Carnot engine is used by the second Carnot engine, whose sink temperature is 200 K. If the net heat absorbed by the first Carnot engine is 200 MJ. What is the heat rejected (in MJ) by the second Carnot engine?
Which of the following gas is used as a working medium in air standard cycle?
An engine based on a standard Otto cycle is operating with air as an medium with specific heat of 1.4 has a cylinder diameter of 5 cm and stroke length of 7.5 cm. If the clearance volume is 88.15 cc and the heat supplied per kg of air per cycle is 900 kJ/kg, then work output (in kJ) per kg of air is?
A closed system contains saturated liquid ammonia at $$10^\circ C$$. The mass of ammonia is 5 kg. The amount of heat that is required to convert all thesaturated liquid to vapour at constant pressure is 16.2 MJ. If the entropy of saturated liquid is 0.88 kJ/kg-K, what is the entropy (kJ/kg-K) of saturated vapour process without heat transfer?
Why the study of air standard cycle is proposed?
How is the rate of burning of fuel controlled in the compression ignition engine?
Which denoted path is followed by the Diesel Cycle in the below P-V diagram?
