26) Francis turbine is best suited for

Answer is:

medium head application from 24 5o 180 m

Explanation:

Francis turbine is best suited for medium head application from 24 to 180 m.

27) For small discharge and high heads which pump is preferred

Answer is:

reciprocating type

28) For a circular cross-section beam subjected to a shearing force F, the maximum shear

Answer is:

(4F)/(Pixdxd)

29) Resilience of a material is important, when it is subjected to

Answer is:

shock loading

Explanation:

The strain energy stored in a body due to external loading within the elastic limit is known as resilience.
Resilience of a material is important, when it is subjected to shock loading.
