A heat exchanger consists of a closed system with a series of parallel tubes connected by 180
Question:
A heat exchanger consists of a closed system with a series of parallel tubes connected by 180° elbows as shown in the figure. There are a total of 14 return elbows. The pipe diameter is 2 cm, and the total pipe length is 10 m. The head loss coefficient for each return elbow is 2.2. The tube is copper. Water with an average temperature of 40°C flows through the system with a mean velocity of 10 m/s. Find the power required to operate the pump if the pump is 85% efficient.
Step by Step Answer:
The head loss due to the elbows can be calculated using the equation head loss K velocity2 2 g ...View the full answer
