What is the expected temperature of water leaving a condenser if 10 pounds of refrigerant loses 20 BTUs per pound and the entering water temperature is 80°F?

To determine the expected temperature of water leaving a condenser, it is essential to understand how heat transfer works in this context. The refrigerant in the condenser loses energy as it passes through, which in this scenario equates to 10 pounds of refrigerant losing 20 BTUs per pound. This results in a total heat loss of:

10 pounds * 20 BTUs/pound = 200 BTUs.

This heat loss is absorbed by the water, causing its temperature to rise. When we assess the effect of this heat transfer, we can calculate the new temperature of the water after absorbing the heat.

We begin by knowing the initial entering temperature of the water is 80°F. To find how much the temperature of the water increases due to the absorbed heat, we apply the principle that the heat absorbed by the water is equal to the heat lost by the refrigerant.

To understand how the temperature rise is determined, we need to know the specific heat of water, which is approximately 1 BTU per pound per degree Fahrenheit. If we assume we have a given flow rate or weight of water, the amount of water influenced by this heat can be calculated. For every BTU absorbed by the water, 1 BTU raises the temperature of
