(b) In the case of no losses, Moody (1965) recommends the following equation for calculating the mass flow rate of wet steam (ie. two-phase water) through the constriction =A 2(h-h) Variable and units are the same as in part (a), but also include the following: he is the specific enthalpy upstream of the constriction h, is the specific enthalpy at the throat v, is the specific volume (m/kg) of the steam at the throat. Express the dimensions of h, and h, in terms of [L]" {M} [e][7].
