15/07/2019 · 63.6174 x 65 = 4135.131 (total pounds pressure on piston.) 4135.131 x 416.6 = 1,722,695.5 / 33,000 = 52.2 (indicated horsepower) Taking off 10% for the friction of the engine, .90 x 52.2 = 46.98 or 47 horsepower. This is the power delivered by the engine - brake horsepower as it is called.

Νatural draught flow rate (draft flow) - calculator - fx

The structure which provides ventilation for hot flue gases or smoke from a boiler, stove, furnace or fireplace to the outside atmosphere causes a flow rate. The height that structure (e.g. chimney) influences its ability to transfer flue gases to the external environment via *stack effect*. The higher pressure outside the chimney is the driving force that moves the required combustion air

11/03/2020 · The coal consumption of a 75-ton coal-fired steam boiler can be obtained through a calculation formula, the formula is as follows: coal consumption of the boiler = boiler power * 3600 / coal combustion heat / boiler efficiency.
