Heat rejected during cooling process Solution

Follow our step by step solution on how to calculate Heat rejected during cooling process?

FIRST Step Consider the formula

Q R, Cooling = ma \cdot C p \cdot (Tt' - T4)

Next Step Substitute values of Variables

∴

Q R, Cooling = 120kg/min \cdot 1.005kJ/kg*K \cdot (350K - 342K)

Next Step Convert Units

∴

Q R, Cooling = 2kg/s \cdot 1005J/(kg*K) \cdot (350K - 342K)

Next Step Prepare to Evaluate

∴

Q R, Cooling = 2 \cdot 1005 \cdot (350 - 342)

Next Step Evaluate

∴

Q R, Cooling = 16080J/kg

LAST Step Convert to Output's Unit

∴

Q R, Cooling = 16.08kJ/kg
