About This Product
Hot water in the vessel and cold water circulating through the coil exchange heat while the agitator stirs the vessel. Measuring the temperatures of the circulated water and the vessel water lets students determine the heat transfer coefficient at various agitator speeds. This HEAT TRANSFER LAB unit needs a drain arrangement for the water and a 230 V, 15 A stabilised supply.
Frequently Asked Questions
Q1. What does the agitated vessel experiment determine? The heat transfer coefficient at various agitator speeds, from the temperatures of the circulated water and the water in the vessel.
Q2. What is the coil made of? A copper tube of 3/8″ dia., formed into a helical coil of 200 dia. with 8 turns, fixed inside the vessel.
