The approximate equation of Rankine (23) begins to be I or 2% in error at the boiling-point under atmospheric pressure, owing to the coaggregation of the molecules of the vapour and the variation of the specific heat of the liquid.
Where and Table Of Properties Of Saturated Steam The values of the coaggregation-volume c, which form the starting-point of the calculation, are found by taking n =10/3 for convenience of division in formula (13).
