An engine operates on a Brayton cycle with an air pressure ratio of 10 and flow rate 1 kg/s. If heat added to the cycle is 5,000 kJ and heat exhausted out from the cycle is 2,500 KJ, estimate the efficiency difference (%) in hot condition and in air standard assumptions, respectively, based on the hot condition. 273 K+ Jost

Q: Air enters the compressor of an air-standard Brayton cycle at P₁ = 14 lbf/in.², T₁ = 520°R, and a…

A: Here, P1 is the initial pressure at entry and T1 is the initial temperature at entry.

Q: The following details were noted in a test on a single-cylinder four-stroke oil engine: bore = 150…

A:

IC engines

The term "engine" indicates a mechanical device/machine used to convert input energy to a specific mechanical output. The input energy may be in the form of chemical energy, thermal energy, or so on and mechanical output is in the form of mechanical energy (work done). Generally, the engines classify into two groups which are internal combustion type and external combustion type, and further, these two types can be classified into two types that are reciprocating and rotary engines.
