CE 321 Lab # 3 Bernoulli’s Equation General Info: - Hand in Pre-lab Questions - Worksheet and Spreadsheets (sent by email) due Thursday by 5 pm - Lab Reports due Tuesday by 5 pm (both Hardcopy and Electronic) - www.egr.msu.edu/cee/techcomm Experiment Objectives: 1- to investigate the validity of Bernoulli’s equation as applied to a tapering horizontal zone 2- to determine if the variations in pressure can be predicted by Bernoulli’s equation for tapering horizontal zone. Theory Bernoulli’s Equation: 2 2 1 1 2 2 1 2 2 2 V P V P z z g g (1) If horizontal tube leveled correctly, then z 1 = z 2 , and Equation 1 is then simplified to 2 2 1 1 2 2 1 2 2 2 V P V P z z g g 2 2 1 1 2 2 2 2 V P V P g g (2) 1 P pressure head or static head = h s 2 1 2 V g velocity head = h v Total head, h T = h s + h v = 2 2 V P g 1/4
