- The critical pressure ratio is given by (where p₁ = Initial pressure of steam, and p₂ = Pressure of steam at throat or critical pressure)
- Fire tube boilers are limited to a maximum working pressure of
- Fire tube boilers are limited to a maximum design working pressure of
- The ratio of heat utilized to produce steam and the heat liberated in furnace is known as
- In order to obtain superheated steam, a superheater is added in an existing boiler. As as result, furnace vacuum will
- When the speed of the engine is controlled by means of a valve in a steam pipe, which regulates the pressure of steam entering the engine, then the governing is known as
