A reversible heat engine operates between 300K and 600K. If heat output is 200 KJ, the heat input is

3) Bernoulli's theorem applies to which type of flow

Answer is:

all of these combined

Explanation:

The Bernoulli's equation states that For a perfect incompressible liquid, flowing in a continuous stream, the total energy of a particle remains the same, while the particle moves from one point to another.
The Bernoulli's equation is applied to venturimeter, orifice meter and pitot tube.
Hence Bernoulli's theorem applies to incompressible, steady and non-viscous flow.

4) Tensile stress in thin spherical shell subjected to internal pressure is

Answer is:

pd/4t

Explanation:

Tensile stress in thin spherical shell subjected to internal pressure is pd/4t

5) Cavitation in a pump is associated with which pressure

Answer is:

vapour

Explanation:

Simply defined, cavitation is the formation of bubbles or cavities in liquid, developed in areas of relatively low pressure around an impeller. The imploding or collapsing of these bubbles trigger intense shockwaves inside the pump, causing significant damage to the impeller and/or the pump housing.
Hence cavitation in a pump is associated with vapour pressure.

6) Petrol engine works on

Answer is:

Otto cycle

Explanation:

Otto cycle is also known as constant volume cycle, as the heat is received and rejected at a constant volume. Otto cycle is used in gas, petrol and many of the oil engines. The petrol engine works on Otto cycle.

The ideal Otto cycle consists of two constant volume and two reversible adiabatic or isentropic processes.

Otto cycle is taken as a standard of comparison for internal combustion engines. For the purpose of comparison with other cycles, the air is assumed to be the working substance.
