### Air velocity calculations pipes

hi guys
i want to calculate air velocity or volume flowrate in 0.5" (2mm thickness) tube. Air is stored at 100 bar pressure.then air pressure is reduced (with the help of Reducing Valve) to 10bar pressure and then air enters 0.75" (2mm thickness) tube. now the tube (0.75") enters into a tank (which is pressurized at 2bar).
Please help me how can i solve my problem. can i use Bernoulli equation. i also found a formula for air velocity calculation which is
V= (25000 DP/L)Squareroot
while
V = Air velocity in feet per second
D = Pipe inside diameter in inches
L = Length of pipe in feet
P = Pressure loss due to air friction in ounces-force/square inc
can i use this one for my calculations
thanks
