Q1: Mass flow through a sonic nozzle is a function of gas pressure and temperature (Pressure = P, Temperature = T). If the mass flow rate through the nozzle is given by: m = 0.0430 70.5 Where: m Ib/min, P = Psia, T = °R a) Determine what the units for the constant 0.0430 are? b) What will be the new value of the constant, now gives as 0.0430, if the variables in the equation are to be substituted with SI units and m is calculated in SI units? Q2: Some of fermentation organism which is used to analyze the waste water from oil refinery can live at reduced air pressure down to 22 Kpa.
