Question 2: Human sweat removes excess body heat through transporting heated sweat to outside body by open channels as depicted in Figure 1 . Liquid sweat is flowing through the sweat channel with an average velocity of 0.5mm/s at 25C and 100kPa. The sweat leaving the body has a temperature of 35C(dsg=20m). Determine the heat transfer rate from the body to the sweat. Figure 1 scmemutic aruwing of muman sweat gland
