MICROTECH apparatus consists of transparent flow channel through which water is made to flow. The velocity of water changes as cross sectional area of channel changes. The changes of head are measured with manometric tubes connected at various tappings along the length of channel. Thus the Bernoullis theorem can be verified by calculating the energy and head of water at different sections.Transparent acrylic flow channel, 75 cm long. (ConvergentDivergent type)
