@laugh_leakk on Instagram: "- The video captures a humorous moment where a group of ducks, initially eager to venture outside into the snow, quickly change their minds and retreat back inside, highlighting their sensitivity to cold temperatures despite their natural adaptations for warmth, such as a countercurrent heat exchange system in their feet that minimizes heat loss. - This behavior contrasts with the common misconception that ducks are always comfortable in cold water; in reality, they r

What is the role of countercurrent heat exchange in porpoises, ... | Filo

SOLVED: Cold" water enters a countercurrent heat exchanger at 5 °C and exits at 65 °C, which uses "hot" water that circulates between the shell and the outside of the tubes entering at 120 °C and comes out at 70 °C. The cold water circulates inside the tubes that are made of brass, with K = 96 W/m °C, with de = 16 mm and thickness δ = 1 mm. It has 55 tubes, and the mass flow of the cold fluid is 7.2 Kg/s. The efficiency is 92%. The internal diameter of the shell is 219 mm with a thickness
