How many Square feet of water is in a ton?

Answer 1

Sq feet refers to area. and your question cannot be answered as you asked it. You need CUBIC feet- a measure of volume. .One cubic foot of water weighs 62.3 pounds (it varies some with the temperature). A ton has 2000 pounds. So divide 2000 by 62.3, and that will give you the number of CUBIC ft of water in a ton.

Answer 2

Most air-conditioners generate about 400 CFM per ton, but don't confuse Square Feet with Cubic Feet. A sunny South-facing room (SF) will take more CFM to cool than the same size room facing North.

A very rough idea is:

- For and older drafty, inefficient house 400SF per ton. Any sizing larger than this should be explained by the contractor.

- For a newer reasonably built house 600SF per ton.

- For an Energy Star Qualified house 600-800SF per ton.

- Well designed, thoughtfully crafted houses can achieve 800-1200 SF per ton.

Bigger is not better - getting the right size is important. About 70% of the work of the air conditioner is to remove the humidity from the air - this is called the latent load. An oversized unit will bring the temperature down quickly but not remove the humidity. A right-sized unit will run longer and do a better job with dehumidification allowing you to keep the set-point several degrees warmer and still achieve the comfort level expected.

Residential cooling and heating loads are calculated using ACCA Manual J (or similar) procedure. This takes in to account many factors including infiltration, ventilation, insulation, glazing, occupants, building orientation and many more.

Commercial cooling and heating loads are calculated using ACCA Manual N (for small commerical) and use many of the same inputs are residential calculations. Greater emphasis is given to internal loads and uses. For example a gym or kitchen will have much different cooling needs than an office or library.

Answer 3

Determining square footage (volume) by weight requires knowing the objects (or materials) density and mass. Volume equals the mass of your object divided by its density.
