Coefficient of contraction = (area of jet at v.c) / (area of orifice).
Coefficient of velocity = (actual velocity of jet at v.c) / (theoretical velocity of jet).
Coefficient of discharge = (actual discharge) / (theoretical discharge).
Coefficient of resistance = (loss of head in the orifice) / (head of water).
