2. Mass flow through a sonic nozzle is a function of gas pressure and temperature. For a given pressure p and temperature T, mass flow rate through the nozzle is given by m = 0.0549 p/(T)0.5 where m is in lb/min, p is in psia and T is in 'R (a) Determine what the units for the constant 0.0549 are. (b) What will be the new value of the constant, now given as 0.0549, if the variables in the equation are to be substituted with SI units and m is calculated in SI units.
