The method by which the control volume energy rate balance accounts for work done as mass flows across a boundary.
Answer to Problem 4.1E
Explanation of Solution
The amount of a substance flowing through a channel per unit of time is known as the mass flow rate. Since energy is an extensive property, it can neither be created nor be destroyed. The energy rate balance of a control volume can be obtained using energy balance criteria and doing some modifications in the closed system energy rate balance equation as follows:

The panel, which has a surface area of 24 ft2, receives energy from the sun at a rate of 200 Btu/h per ft2 of collector surface. Twenty-five percent of the incoming energy is lost to the surroundings. The remaining energy is used to heat domestic hot water from 90 to 120°F. The water passes through the solar collector with a negligible pressure drop. Neglecting kinetic and potential effects, determine at steady state how many gallons of water at 120°F the collector generates per hour.arrow_forward
