Assuming steam is saturated in both cases, and if steam and water are mixed, and the mix reaches a final temperature of 160 o F, the heat supplied by steam should be increased by the sensible heat from its saturation condensation temperature down to 160 o F. In that case, the 150 psig-steam would supply a bit more heat per pound.
