1. For the flow of oil (viscosity = 100 cP, SG = 0.85) through a long straight smooth 5-cm ID pipe at 10 m3/hr, what is the pressure drop per meter is approximate?

2. Water at 20oC (SG = 0.998, viscosity = 1 cP) flows through a certain pipe 200 m long and 5-cm ID at 500 gallons per minute. If the friction head loss is 20 m, what is the Fanning friction factor?
