Q1: oil with vis cosity (2m10?Ns/) and density af (850 kg) is Pumped along astraight herizontal Pipe with flow rate of (5LIS). The static Pressure differen ce between twe tapping points (10m) appart is (80 N/m). As5uming lamin ar How, detumine the Plowings: i) The pipe diameter. i) The Reynoldinumber- Q2: The velocity Profile in a laminar boundary layer on a flat plate is to be modelled by the cubic exprission: Explain; why a. and az are zero and evaluate the constants di and d3 in terms of the boun dary lay er thick ness 8.
