Maximum Possible Rate of Heat Transfer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Possible Rate of Heat Transfer = Minimum Capacity Rate*(Inlet Temperature of Hot Fluid-Inlet Temperature of Cold Fluid)
Q_Max = C_min*(T_hi-T_ci)
This formula uses 4 Variables

Variables Used

Maximum Possible Rate of Heat Transfer - (Measured in Joule per Second) - Maximum Possible Rate of Heat Transfer is defined as the maximum amount of heat that is transferred per unit of time in some material.
Minimum Capacity Rate - (Measured in Watt per Kelvin) - Minimum Capacity Rate is defined as the minimum quantity of heat required to raise the temperature of an object by 1 degree celcius or by 1 Kelvin per unit time.
Inlet Temperature of Hot Fluid - (Measured in Kelvin) - Inlet Temperature of Hot Fluid is the temperature at which the hot fluid enters the heat exchanger.
Inlet Temperature of Cold Fluid - (Measured in Kelvin) - Inlet Temperature of Cold Fluid is the temperature at which the cold fluid enters the heat exchanger.

STEP 1: Convert Input(s) to Base Unit

Minimum Capacity Rate: 1000 Watt per Kelvin --> 1000 Watt per Kelvin No Conversion Required
Inlet Temperature of Hot Fluid: 343 Kelvin --> 343 Kelvin No Conversion Required
Inlet Temperature of Cold Fluid: 283 Kelvin --> 283 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_Max = C_min*(T_hi-T_ci) --> 1000*(343-283)

Evaluating ... ...

Q_Max = 60000

STEP 3: Convert Result to Output's Unit

60000 Joule per Second --> No Conversion Required

FINAL ANSWER

60000 Joule per Second <-- Maximum Possible Rate of Heat Transfer
