I need to solved this question quickly please

Extracted text: Q1: oil with viscosity (2m10 N.s/) and densily of (850 ka m) is Pumped along astraight herizen kal Pipe with flow rate of (5LI). The static Pressure differen ce between two tapping points (10m) appart is (80 N/m). Assuming lamin ar How, detumine the flowings: i) The pipe diameter. i) The Reynold'i number.
