Following Mechanical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

1.The thermodynamic difference between a Rankine cycle working with saturated steam and the Carnot cycle is that

carnot cycle can't work with saturated steam
heat is supplied to water at temperature below the maximum temperature of the cycle
a rankine cycle receives heat at two places
rankine cycle is hypothetical
none of the above.

2.Otto cycle consists of following four processes

two isothermals and two isentropics
two isentropics and two constant volumes
two isentropics, one constant volume and one constant pressure
two isentropics and two constant pressures
none of the above.

3.Gas turbine cycle consists of

two isothermal and two isotropic
two isentropics and two constant volumes
two isentropics, one constant volume and one constant pressure
two isentropics and two constant pressures
none of the above.

4.The cycle in which heat is supplied at constant volume and rejected at constant pressure is known as

Dual combustion cycle
Diesel cycle
Atkinson cycle
Rankine cycle
Stirling cycle.

5.For same compression ratio and for same heat added

Otto cycle is more efficient than Diesel cycle
Diesel cycle is more efficient than Otto cycle
efficiency depends on other factors
both Otto and Diesel cycles are equal�ly efficient
none of the above.
