WebMay 22, 2024 · Online monitoring of commercial heat exchangers is done by tracking the overall heat transfer coefficient, because the overall heat transfer coefficient tends to decline over time due to fouling.Fouling is the accumulation of unwanted material on solid surfaces to the detriment of function. The fouling materials can consist of either living … Web= 0.17W/m⋅K ). The inner and outer heat transfer coefficients are h i =1500W/m2 ⋅K and h o = 20000W/m 2 ⋅K , k m = 8W/m⋅K , respectively. a) Determine the ratio of plastic to metal tube surface areas needed to transfer the same amount of heat. b) Determine the ration of plastic to metal mass associated with the two heat exchanger designs. period 6 weeks after birth
