How Many CFM Is A KW?

How do you convert BTU to CFM?

Heating BTUs = CFM x ∆t x 1.08 of air per CFM x .

24 (the specific heat of air) x 60 (minutes in an hour.) This factor will vary at higher altitudes and temperatures..

What is cooling capacity in kW?

Cooling capacity is the measure of a cooling system’s ability to remove heat. The SI unit is watt (W). Another unit common in non-metric regions or sectors is the ton of refrigeration, which describes the amount of water at freezing temperature that can be frozen in 24 hours, equivalent to 3.5 kW or 12,000 BTU/h.

How many kW is in a ton?

3.5169 kilowattsConversion Ton to Kilowatt The ton (ton of refrigeration) is a unit of power. This tool converts tons to kilowatts (ton to kw) and vice versa. 1 ton ≈ 3.5169 kilowatts. The user must fill one of the two fields and the conversion will become automatically.

Can you convert psi to CFM?

The relationship between CFM and PSI is just linear. … if you get 8 CFM at 120 psi, you will get 4 CFM at 60 PSI. The pressure just “pushes” the air out, and with half the “push” you get half the air flow.

How do you calculate BTU to CFM?

Since the energy in natural gas is equivalent to the gas’s volume, you can freely convert between BTUs per hour and cubic feet per minute (CFM). Divide the energy transfer rate in BTUs per hour by 100,000, which is the number of BTUs in a therm.

Is 300 watts a lot of power?

For example, most refrigerators use 300–780 watts, but let’s say you were one of the lucky ones who scored one that uses only 300 watts. To calculate how many watts your refrigerator uses per day, you would multiply the wattage (300) by the hours (24), to figure that you are using 7,200 watt-hours per day.

How much is 700 watts per hour?

What’s bigger kW or W?

One kilowatt (kW) equals 1,000 watts, and one kilowatt-hour (kWh) is one hour of using electricity at a rate of 1,000 watts. … One megawatt (MW) = 1,000 kilowatts = 1,000,000 watts. For example, a typical coal plant is about 600 MW in size. Gigawatts measure the capacity of large power plants or of many plants.

How many kW is a 4 ton AC?

Central Air-Conditioners use on average 1-kilowatt hour (kWh) per ton per hour. A 4-ton air-conditioner will use approximately 4 kWh per hour.

How many watts is a cfm?

One factor that affects this number is how big the fan is. That 35 cfm/watt fan was a tiny 24″, whereas the 106 cfm/watt fan was 52″. The range of efficiencies for the larger fans, according to the label, is 51 to 176 cfm per watt for fans that are 49″ to 60″.

How do you calculate CFM from motor kw?

If we want to calculate the CFM (Cubic Feet per Minute) for a 4 cycle motor we can multiply the cubic inch displacement of the engine by the maximum rpm (Revolutions Per Minute) and divide the result by 3456. Then we multiply the results by the volumetric efficiency of the motor.
