Parallel Flow and Counter Flow Heat Exchanger Heat exchanger is gadgets in which warm is exchanged starting with one liquid then onto the next.. The device comprises of a concentric tube warm exchanger. High temp water courses through internal tube one way just and chilly water streams over the inward tube in external tube. Bearing of cool liquid stream can be changed from parallel or counter to boiling water with the goal that unit can be worked as parallel or counter stream warm exchanger. Stream rates of hot and cool water are estimated utilizing Rotameters. An attractive drive pump is utilized to course the high temp water from a re-cycled type water tank, which is fitted with radiators and Digital Temperature Controller. Trial: To figure the accompanying parameters both for parallel and Counter stream plan. To discover the rate of warmth exchange To figure the LMTD Overall warmth exchange co-proficient. To think about the execution of Parallel and Counter stream warm exchanger Utilities Required: Water supply 10 lit/min (approx.) and deplete Electricity Supply: 1Phase, 220 V AC, 3 kW Floor zone 2 m x 0.6m Heat Transfer Lab gear manufacturers,exporters and Heat Transfer Lab providers
