Python question: confused as to how to compute the three values of velocity for pressure drop?

2. Compute the pressure loss for water flowing through a pipe at three different speeds. The pressure loss, Ap, for flow through a horizontal pipe can be computed using the following expression: L V2 2 where p is the density of the fluid, f is a friction factor representing losses, L is the length of the pipe, D is the diameter, and V is the mean velocity of the flow Assuming turbulent flow in a smooth pipe, the friction factor, f, can be correlated to 0.316 Re0.25 Reynolds number, Re, as where Reynolds number is related to the diameter of the pipe: Re-pVDI Assuming water at 20C, the density (p) is 999 kg/m3 and the viscosity (p) ?s 10x10-3 kg/( The pipe is 20 m in length and 50 mm in diameter. Write a Python program to com- pute the pressure drop at three flow speeds: V 1.2 m/s V = 1.8 m/s
