Determine how long it will take for the thermocouple to read 99% of the initial temperature difference.
A test is carried out to determine the overall heat transfer coefficient in a new automotive radiator that is a compact cross-flow water-to-air heat exchanger with both fluids (air and water) unmixed. The radiator has 40 tubes of internal diameter 5 mm and length 650 mm, in a closely spaced plate-finned matrix. Hot water enters […]
