The velocity of steam leaving the nozzle (V) is given by (where K = Nozzle coefficient or nozzle efficiency and hd = 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 $${\text{K}}{{\text{h}}_{\text{d}}}$$
