Mechanical Engineering : Thermodynamics QUESTIONS AND ANSWERS :: part6 : 1 to 5
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. |
