Determine change in velocity across ideal divergent nozzle with inlet enthalpy of 1,204 Btu/lbm and exit enthalpy of 1,203.91 Btu/lbm
I know that delta v^2=(.09btu/lb)*(2)*(32.2lbm*ft/lbf sec^2)(778ftlbf/btu)
so: deltav^2=4509.29ft^2/sec^2
taking the sqrt deltav=67.15ft/sec
My problem is this: I need to convert the above problem to SI units
So far: (.21kj/kg)*(2)*(9.81m/sec^2)=4.1202
Any help would be appreciated!
