This laboratory exercise is used to investigate convection heat transfer in a cross flow heat exchanger. The performance of a cross flow heat exchanger is largely dependent on the configuration

of the tubes across the duct and the speed of the cooling air flowing within the duct. The heat transfer is not uniform throughout the tube array, and hence, it is necessary to find an effective value for the entire heat exchanger over a range of airflow rates. Additionally,the overall performance of any heat exchanger must involve a determination of the static pressure drop through the apparatus. Upon successful completion of the experiment you should be able: 1. To understand convection heat transfer in a cross flow heat exchanger. 2. To investigate the cross flow heat exchanger at different speeds of the cooling air flow andat different positions of the air duct. 3. To determine the convection heat transfer coefficients for the tested conditions. Important Link to watch to do labhttps://youtu.be/SaLJ3MkYHWwhttps://youtu.be/qTUDTTJ-ewUhttps://youtu.be/ZPvTwEtpxqg
