Given Thrust-specific fuel consumption cT=0.5279lb/lbf*h... as other units in the question are in SI unit, I have to convert it to (N/s)/N first...
1 lbf = 4.448 N
1 lbm = 0.4536 kg
Thrust-specific fuel consumption = weight of fuel burned per unit time (N/s) per unit thrust (N)
The Attempt at a Solution
cT=0.5279lb/lbf*h= (0.5279lb/lbf*h)* (4.448 N/lbf) / (0.4536 kg/lbm) / (3600s/h) = 1.49e-5 kgN-1s-1
which the unit of my answer stands for mass per force per time (kg/Ns) instead of force per time per force(N/Ns)...
where in the unit conversion have i done wrong??? thank you very much!
