Answer:
(b) Constant (minimum) volume
Explanation:
In the idealized Otto cycle there are 4 process that are
- Reversible adiabatic compression
- Addition of heat at constant volume
- Reversible adiabatic expansion
- Rejection of constant volume
So from above discussion we can see that heat is added when there is constant (minimum) volume which is given in option (b) so option (b) will be the correct answer
Answer:
Given:
efficiency of the turbine, 
= 65% = 0.65
available gross head, 
= 45 m
head loss, 
= 5 m
Discharge, Q = 
Solution:
The nozzle is 100% (say)
Available power at the inlet of the turbine, 
is given by:
(1)
where
= density of water = 997 
acceleration due to gravity, g = 
Using eqn (1):
Also, efficency, is given by:

An electromagnet is a made coil associated with a ferromagnetic core. This way, the strength of the magnet is controlled by the input current. A solenoid is a simple shape used in magnetostatics or magnetics. ... A solenoid is a cylindrical coil of wire whose diameter is small compared to its length.
