ABSTRACT

Capacity of tanks and cylinders

Rectangular container gallons = length x width x height divided by 4546

Rectangular container litres = length x width x height divided by 1000

Cylindrical container gallons - radius x radius x height divided by 5788

Cylindrical container litres = radius x radius x height divided by 1273

(All above dimensions to be in centimetres)

Power required

Minutes required to heat water = litres x temperature rise in degrees centigrade divided by 14.33 x kW x efficiency

Loading required in kW to heat water = litres x temperature rise in degrees centigrade divided by 14.33 x minutes x efficiency
