Fluid Friction Apparatus: 
Shows flow and losses in different pipes, fittings and valves. Shows popular flow measurement instruments 

• Should includes different valves, pipes and fittings to show losses 
• Includes experiments on roughened pipes 
• Uses Bernoulli's equation 
• Shows how to use Venturi and orifice meters to measure flow 
• Includes a traversing Pitot tube to measure velocity profile 
• Numbered pressure tappings are fitted at all the important points (35 off), for measurement of the pressure change along each pipe section or pipe component. 
• Each pressure tapping Includes a special self sealing connector. 
• To measure the pressure change across each pipe section or components, a free standing 3 way Plezometer unit is supplied. 
• To measure the higher differential pressure across the valves and strainer, a differential pressure gauge is included.
