What must be the pressure difference between the two ends of a 2.0-km section of pipe, 25 cm in diameter, if it is to transport oil?

Respuesta :

theoooooo
flow rate F = .00087 m^3/s 
viscosity eta = 0.2 Pa-s 
pipe radius r = 0.105 m 
pipe length L = 2800 m 
dP = 8LF*eta/(pi*r^4) = 10206.8139295042 Pa
