KPCL AE Mechanical Question Paper - 2018 with Answer Key

12) In a 50% reaction tu rbine stage, tangential component of absolute velocity at rotor inlet is 537 m/s and the blade velocity is 454 m/s. The power output in kW of steam will be

Answer is:

282 kW

13) The kinematic viscosity is the

Answer is:

Ratio of absolute viscosity to the density of the liquid

Explanation:

Absolute viscosity or dynamic viscosity is defined as the property of a liquid which offers resistance to the movement of one layer of liquid over another adjacent layer of liquid. The viscosity of a liquid is due to cohesion and interaction between particles.
Kinematic viscosity is defined as the ratio of absolute viscosity to the density of the liquid.

14) The size of cam depends upon
