The velocity of steam leaving the nozzle (V) is given by (where K = Nozzle coefficient or nozzle efficiency and h_d = Enthalpy or heat drop during expansion of steam in a nozzle)

A) V = 44.72 $${{\text{h}}_{\text{d}}}\sqrt {\text{K}} $$ B) V = 44.72 $${\text{K}}\sqrt {{{\text{h}}_{\text{d}}}} $$ C) V = 44.72$$\sqrt {{\text{K}}{{\text{h}}_{\text{d}}}} $$ D) V = 44.72 $${\text{K}}{{\text{h}}_{\text{d}}}$$
