The rate entropy increases per unit time.
Answer to Problem 41P
The rate entropy increases per unit time is
Explanation of Solution
Given information:
Rate of
Temperature of heat source,
Temperature of water,
Formula used:
Write the expression to calculate the rate of change of entropy per unit time.
Calculation:
Consider the conversion factor to convert rate of conduction from
Since, the heat is transferred from source to water. Therefore, the rate of change of entropy of source is negative.
Substitute the values in equation (1).
Therefore, therate entropy increases per unit time is
