Given:
size of scale model = 4(size of pump)
power ratio of pump and scale model = 5:1
Solution:
Let the diameter of scale model and pump be
and
respectively
and head be
and
respectively
Now, power, P is given as a function of head(H) and dischagre(Q)
P =
(1)
From eqn (1):

and

So,

Therefore,
= 
= 
= 
= 
= 
Answer: Technician A

Answer: (b)
Explanation:
Given
Original length of the rod is 
Strain experienced is 
Strain is the ratio of the change in length to the original length

Therefore, new length is given by (Considering the load is tensile in nature)

Thus, option (b) is correct.
