CONCENTRIC TUBE HEAT EXCHANGER APPARATUS

Price: 100 INR/Piece

This is the simplest of the optional heat exchangers. It has two tubes, one inside the other. One tube carries hot fluid, the other carries cold fluid. Heat transfers between them. Teknik heat exchanger is in two equal parts joined by intermediate pipes. This allows two extra measurement points at the midpoint (plus the standard four points at the connectors). This gives more useful experiment results, to show more clearly how the fluid temperatures change during heat transfer. The Service Module (TD360) provides hot and cold water to the heat exchanger and all the instruments needed to measure its performance. All fluid connections to the heat exchanger are self-sealing quick connectors - for safety and simplicity. The hot and cold fluid streams have different connectors to reduce errors. Connecting the heat exchanger takes less than one minute. The heat exchanger is on a bedplate that has a clear schematic diagram showing the connections. The bedplate fixes to the Service Module with thumbscrews.

Heat Transfer Through Lagged Pipe

Price: 100 INR/Unit

Heat Transfer Through Lagged Pipe Micro Teknik The setup is designed and fabricated to study lagging phenomenon in case of pipes. It consists of three concentric pipes of small thickness as compared to diameter and are arranged concentrically, and closed with the help of two discs. Two different insulating materials fill the annuli between the cylinders compactly. Temperature Sensors are fitted to measure the temperature of pipe walls for radial outward heat flow measurement. Inside the inner pipe, a Nichrome wire heater is placed axially. Heat input to the heater is given through a variac and measured by Digital Voltmeter and Digital Ammeter. By varying the heat-input rates, wide range of experiments can be performed Experiments To estimate the actual rate of heat transfer through the composite cylinders from the measured interface. temperature of the known value of thermal conductivity of the two insulating materials. To determine the effective thermal conductivity of the composite cylinders. To determine the theoretical temperature profile within the composite cylinders. Utilities Required.
