Explain Dalton's law of partial pressure. How it is applicable to condenser?
It states that’ “The pressure exerted by mixture of air and steam is equal to sum of partial pressures, which each constitute would exert, if it occupies the same volume”.
In condenser total pressure is the sum of partial pressure of steam and air.
Mathematically,
Pc= Pa + Ps
Where;
Pc = Pressure in condenser containing mixture of air and steam
Pa = Partial pressure of air
Ps = Partial pressure of steam
