A steam condenser must remove 5000 kW of heat. If the cooling water temperature rise is limited to 10 °C, what is the required mass flow rate of cooling water? (c = 4.187 kJ/kg· K)
- 1194.17 kg/s
- 500.00 kg/s
- 59.71 kg/s
- 119.42 kg/s
Answer
D. 119.42 kg/s
Solution
m = Q/(c T) = 5000/(4.187 × 10) = 119.42 kg/s.
