SYNOPSIS

function crvel67(p, h, ga)

   doubleprecision,intent(in)  :: p
   doubleprecision,intent(in)  :: h
   doubleprecision,intent(out) :: ga
   doubleprecision             :: crvel67

DESCRIPTION

Function crvel67 will calculate the critical flow velocity and isentropic exponent of wet of super heated steam at pressure P amd enthalpy H.

    DEFINITION AND PURPOSE:
       o VC,GAMMA=f(P,H)
       o Calculates critical velocity and isentropic exponents (GAMMA) of
         wet or superheated steam. GAMMA is defined such that PV**GAMMA = C.

REGION OF APPLICATION:

See Section 3.12

CALLING SEQUENCE: VC = CRVEL(P,H,GAMMA)

OPTIONS

P water pressure, in psia.
H enthalpy, in BTU/pound.

RETURN VALUES

GA isentropic exponent.
CRVEL67
  critical flow velocity.
