Heavy fuel oil is pumped at a flow rate of 88 L/s through a new steel pipe. What diameter of the pipe is to be used if the equivalent head loss for a pipe length of 300 m is not to exceed 200 kPa? use f= 0.033

2. Glycerin at 20°C flows upward in a vertical 75-mm diameter pipe with a centerline velocity of 1.0 m/s. Determine for a 10-m length of pipe a. The head loss b. Pressure drop

Problem 5. A horizontal rough pipe with surface roughness of 1.5 × 104 m is used to transport pressurized air at a flow rate of 7 × 102 m³/s. The design guidance requires that the pressure drop must be no more than 4.2 kPa per 50 m length of the pipe. Determine the minimum diameter of the pipe

If the volume flow rate and friction factor is kept the same in a laminar flow pipe but the pipe diameter is doubled, the pressure drop will be:
