Answer to Problem 19SP
Solution:
Explanation of Solution
Given data:
Quantity of water falling every second is 1088 m3.
The distance from which the water is falling is
Formula used:
Write the expression for work potential energy of a substance as
Here,
Write the expression for heat gain or lossif a body or substance undergoes temperature change as
Here,
Explanation:
The temperature rise takes place due to the change in potential energy of water.
The expression for potential energy of a substance is as follows:
The expression for heat required to raise the temperature of water is as follows:
From the question, the potential energy is used to raise the temperature of water is
Consider the calculation for unit time:
Substitute
Refer to Table 18-1 in the textbook for the value of specific heat capacity of water as
Substitute
Conclusion:
The temperature rise in the waterdue to drop is
