Title 2.1 pressure loss in pipes.pdf ✅

Unit 2 2.1 Flow through pipes - pressure loss in pipes
Loss in pipe and fitting A. Major Energy Losses This loss is due to friction. B. Minor Energy Losses These losses are due to : 1. Sudden enlargement of pipe, 2. Sudden contraction of pipe, 3. Bend of pipe, 4. Pipe fittings 5. Obstruction in pipes etc.,

Darcy Weisbach Formula Pressure acting at section 1-1 p1 = F A Pressure acting at section 2-2 p2 = F A Resolving all forces in horizontal directions p1A- p2A-F = 0 (p1 - p2 )A= F1 F1 = f’ x P L x v2 F1 = f’ x P L x v2 = (p1 - p2 )A f’ x P L x v 2 A =(p1 - p2 )
