Calculation Steps

1

Calculate Heat Transfer

Formula:

Q = \dot{m} \times c_p \times \Delta T

Calculation:

Q = 1000 \times 1 \times 20

Result:

20000.00 \text{ BTU/hr}

2

Calculate Tonnage

Formula:

Tons = \frac{Q_{BTU/hr}}{12,000}

Calculation:

Tons = \frac{20000.00}{12,000}

Result:

1.67 \text{ tons}

3

Convert to Kilowatts

Formula:

kW = Q_{BTU/hr} \times 0.000293071

Calculation:

kW = 20000.00 \times 0.000293071

Result:

5.86 \text{ kW}
