Thermodynamics 2Question one a).Process 1- 2 = Isentropic compression Process 2- 3= Reversible constant pressure heating Process 3-4 = Isentropic expansion Process4-1 = Reversible constant volume cooling[ CITATION Ros11 \l 1033 ].b). From Ƞ=1- (rcy−1)yrvy−1(rc−1) × 100Where y=1.4, rv= 14:1, rc = 1:7 Ƞ=1- (0.1421.4−1)1.4×141.4−1(0.142−1) × 100

The i.p. and the mechanical efficiency of a multi-cylinder automobile engine is obtained in a veryshort time through this morse test. When conducting the test the engine is made run at a maintained speed and at the same opening of the throttle[ CITATION Shy16 \l 1033 ]. Initially, the b.p. of the engine having all cylinders functioning is determined through a means of a dynamometer. Next, the b.p. of the engine is obtained with each cylinder condensed inoperative one by one by shorting the spark plug (petrol engine) or by cutting off the supply fuel ( diesel engine). When any cylinder is considered inoperative, the speed brusquely reduce. Before measuring any reading, the initial velocity should be reestablished by amending the load[ CITATION NEL12 \l 1033 ].It is presumed that the f.p. of the inoperative cylinder is kept constant as it were when thecylinder was functioning. For the case of a 4-cylinder engine[ CITATION Sam10 \l 1033 ].

Thermodynamics 4Advantages of Morse TestThe following are some of the advantages of the Morse tests 1. CheapThis test is a relatively cheaper way of obtaining some critical information about the engine alongside the full analysis of the engine[ CITATION Mah10 \l 1033 ].3. Safer Through conducting the morse test, cases of an accident in the engine are highly reduced[ CITATION Chi12 \l 1033 ].4. Faster.
