Question: Repeat Problem for a flow rate of 20 kg/s.
Problem: Water is heated at a rate of 10 kg/s from a temperature of 15°C to 35°C by passing it through five identical tubes, each 5.0 cm in diameter, whose surface temperature is 60.0°C. Estimate
(a) the steady rate of heat transfer and
(b) the length of tubes necessary to accomplish this task.
