Description: The body of the bench should form a reservoir or Sump Tank with a submersible pump. Should have a rim around the top to contain any spilled or excess water. A small recess or Trough in the top should work with are movable drain valve to trap a small volume of water. It should also catch discharged water from some experiments in the fluid mechanic’s range. A hand-operated control valve should adjust the water flowrate from the pump. An electrical box on the side of the bench should include the pump switch, circuit protection and a digital display of flow. A sight gauge to the lower side of the bench should allow the user to check the water level inside the tank. An electronic flowmeter should measure the outlet flow from the submersible pump and the signal from the flow meter should pass to the digital display to show the flow rate.
Features:
For accurate measurements and quicker experiments system should have an electronic flow meter and digital display. Should be made of lightweight fiberglass for strength, easier transport and long life. Should have lockable wheels for mobility with stability and flat top to hold different experiment modules. Should be self-contained with re-circulating water circuit and should not need any external water supply to save mains water.
