Answer:
Net efficiency of generating unit = 42.08 - 5 = 37.08 %
Explanation:
We have given that efficiency of the boiler = 91.2 % = 0.912
Carnot efficiency = 46.9 % = 0.469
Efficiency of generator = 98.4% =0.984
We have to find the efficiency of total generating unit
For finding the efficiency of total generating unit we have to multiply all the efficiencies
So efficiency of generating unit = 0.912×0.469×0.984 = 0.4208 = 42.08 %
For plant losses we have to subtract 5%
So net efficiency of generating unit = 42.08 - 5 = 37.08 %
Answer:
A four-stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle.

true
Explanation:
Creep is known as the time dependent deformation of structure due to constant load acting on the body.
Creep is generally seen at high temperature.
Due to creep the length of the structure increases which is not fit for serviceability purpose.
When time passes structure gain strength as the structure strength increases with time so creep tends to decrease.
When we talk about Creep rate for new structure the creep will be more than the old structure i.e. the creep rate decreases with time.
