Answer:
Combination circuit; The basic strategy for the analysis of combination circuits involves using the meaning of equivalent resistance for parallel branches to transform the combination circuit into a series circuit.
Example:
The use of both series and parallel connections within the same circuit. In this case, light bulbs A and B are connected by parallel connections and light bulbs C and D are connected by series connections. This is an example of a combination circuit.
Answer:
a fracture will occur, because the Kc value is greater than the KIC (48.9901 MPa > 40 MPa)
Explanation:
the solution is in the attached Word file
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,
= 
=
= 
= 
=
