How To Calculate Business Energy Consumption | Diversegy
Remember, 1,000 watts = 1 kilowatt, so we need to divide by 1,000. Using the above example, the equation to determine peak kW is: (300,000 watts) / 1,000 = 300 kW. Kilowatts are important to forecast because they determine the other half of your electricity bill, utility distribution, or delivery costs.
Chiller Cooling Capacity
Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. Q = (16,649FT3/h x 62.414lb/ft3) x 1.0007643BTU/lb.F x (53.6F – 42.8F) Giving us a cooling capacity of 8,533,364BTU/h. see full calculations below. chiller cooling capacity calculation imperial units how to calculate cooling capacity of a chiller.

Cooling Load Calculation
wattage = the rated power of the fan motors (Watts) 1000 = convert from watts to kw. In this cold room evaporator we''ll be using 3 fans rated at 200W each and estimate that they will be running for 14 hours per day. Calculation: Q = fans x time x wattage / 1000. Q = 3 x 14 hours x 200W / 1000. Q = 8.4kWh/day.
Manufacturing Costs: Types and Cost Calculation (+ examples)
The company purchases $1,000 worth of new materials to make product X. Now, the total inventory value is: $1,500 + $1,000 = $2,500. After manufacturing product X, let''s say the company''s ending inventory (inventory left over) is $500. This means, the cost of direct materials is: $2,500 – $500 = $2,000.
