### Open Channel Flow LAB REPORT

Aim TO study the open channel flow in a rectangular channel Objectives 1. Investigate the uniform flow condition in open channel flow 2. Verify the manning’s equation Theory on Open Channel Flow According to Dr. Khalil M. ALASTAL (n.d) an open channel is like a duck with flowing fluid and whose surface is exposed to atmosphere. As the atmospheric pressure remains constant through the length of duct so the fluid flows only due to the difference in potential energy. According to Ivan Gramatikov (n.d) flow rate of water in a channel is the product of its area with the velocity of water through that area Q=A×V Where A is area of cross section and V is velocity of the fluid. Volumetric flow rate is the ratio of volume of flowing fluid to the time taken Q=∆V/t. Area of the rectangular channel is the product of its width with the depth of the water flowing through that area A=b ×y_o. Where b is the width of the rectangular channel and y_o is the depth of the flow. According to David Kni
