Im trying to calculate BTU for chiller that has to do following thing: Cool 200 tons of sea water from 22C to 2C in 24 hours. There are 2 options: A) 22C inlet and 2C outlet temp with water flow 200 ton/day B) Big water tank and recirculating water. Would you be so kind to help me with a rough estimate. Thank you, Best regards

Divide this measurement in half to calculate the radius of the cylinder. Step 3. Measure the height of the drum in feet. Step 4. Calculate the volume of the drum by squaring the radius. Multiply it by pi (3.14). Multiply that number by the height of the drum. This number is the capacity of your dryer in cubic feet.

Cooling Tower Tons. A cooling tower ton is defined as: 1 cooling tower ton = 1 TONS evap = 1 TONS cond x 1.25 = 15000 Btu /h = 3782 k Calories /h = 15826 kJ/h = 4.396 kW . The equivalent ton on the cooling tower side actually rejects about 15000 Btu/h due to the heat-equivalent of the energy needed to drive the chiller's compressor. This equivalent ton is defined as the heat …

Example: If you're taking a shower ( flow and 110˚F hot water) and simultaneously use two faucets ( flow and 110˚F hot water), you will need at least 5 GPM tankless water heater. Tankless heaters can deliver anywhere from 2 GPM to 12 GPM of hot water. How many GPM do you need? The 5-10 GPM ones are most appropriate for the majority of s.

Size your range hood based on the heat output of your range. The first guideline for sizing a range hood depends on the output of your range as measured in British thermal units (BTUs). The recommendation by the Home Ventilating Institute (HVI) is to divide the BTU rating of your stove by 100 to arrive at a minimum guideline for CFM rating.
