//Variable declaration:
q = 0.486 //Flow rate of fluid (ft^3/s)
D = 2.0/12.0 //Diameter of tube in feet (ft)
pi = 3.14 //Value of pi
p = 70.0 //Density of fluid (lb/ft^3)
u = 0.1806 //Viscosity of fluid (lb/ft)
//Calculation:
V = 4*q/pi/D**2 //Flow velocity (ft/s)
Re = D*V*p/u //Reynolds Number
//Result:
if(Re<2100) then
printf("The flow is laminar.")
elseif(Re>2100) then
printf("The flow is turbulant.")
