Calculate the ideal efficiency of a ship’s boiler when steam comes out at 530 K, pushes through a steam turbine, and exits into a condenser that is kept at 290 K by circulating seawater.
The ideal efficiency of a ship’s boiler.
Answer to Problem 27A
The ideal efficiency of a ship’s boiler is
Explanation of Solution
Given:
The temperature of the Steam from the boiler
The temperature of the steam exiting into the condenser
Formula used:
The ideal efficiency of a heat engine is given by the expression,
Calculation:
Substitute the values of the variables in the formula and calculate the ideal efficiency.
Express the efficiency of the engine in percentage.
Conclusion:
Thus, ideal efficiency of a ship’s boiler is
