What is the heat load in a cooling tower that circulates 30,000 GPM with cooling water exiting the tower at 70 degrees F and the warm cooling water returning to the tower at 95 degrees F?
A. 750 MBTUs/min
B. 4,998 MBTUs/min
C. 6,247 MBTUs/min
D. 7,497 MBTUs/min
A. Incorrect. The heat load in a cooling tower that circulates 30,000 GPM with cooling water exiting the tower at 70 degrees F and the warm cooling water returning to the tower at 95 degrees F is 6,247 MBTUs/min. ((30,000 * 8.33) * 25 (Temperature Difference) * 1 (Heat transfer coefficient))
B. Incorrect. The heat load in a cooling tower that circulates 30,000 GPM with cooling water exiting the tower at 70 degrees F and the warm cooling water returning to the tower at 95 degrees F is 6,247 MBTUs/min. ((30,000 * 8.33) * 25 (Temperature Difference) * 1 (Heat transfer coefficient))
C. Correct. The heat load in a cooling tower that circulates 30,000 GPM with cooling water exiting the tower at 70 degrees F and the warm cooling water returning to the tower at 95 degrees F is 6,247 MBTUs/min. ((30,000 * 8.33) * 25 (Temperature Difference) * 1 (Heat transfer coefficient))
