    The Sanzin (Giesel) formula is quite usefull for feetinch locomotives as well.
    Evaporative area of a V2 is 225 square meter and grate 3.8.
    The formula gives a usefull hourly steam rate of 13.3 ton that is 29300 lbs.
    BR test report says 31000 lbs making 1990 indicated horsepower.
    The Rugby test was on rollers with washed coal fresh from fridge and two young firemen
