Find the time required to increase the oil temperature from
Answer to Problem 1P
The time required to increase the oil temperature from
Explanation of Solution
Given information:
The width of the parabolic trough
The insider diameter of the pipe
Initial temperature
Calculation:
Take the mid day irradiance of incident radiation as
The inside diameter of the pipe is 1 cm.
Find the volume of oil in a 1 m pipe section
Take the density of oil
Express the formula for energy
Here, the mass is
Write the expression for power
Here,
The mass is the product of density and the volume. Therefore,
Substitute
Therefore, the time required to raise the oil temperature is
