The flow of a liquid in a laminar flow between infinite parallel plates is resulting a pressure drop due to the viscosity of the liquid and an unseen retarding force. Write an expression of pressure drop. Derive the relationship between local and maximum velocity and determine the ratio of maximum velocity to average velocity. (5+3+2 marks)

Pressure drop varies linearly with velocity for laminar flow in a pipe flow. At a large Reynold’s number encountered in turbulent flow, how do you anticipate pressure drop to vary with flow velocity? Just need a general direction help.

A light oil is flowing through a commercial steel pipe of diameter D1. The head available to produce flow is independent of the flow rate. It is decided to utilise this head to increase the oil flow rate fourfold by installing a second pipe in parallel with the first pipe and of the same length. What should the diameter of the second pipe be, if: (i) flow in each of the two pipes is highly turbulent and the same roughness...

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...
