Scraped Surface Heat Exchangers are used for fluids which are generally heat ________ Correct Answer Sensitive

Scraped Surface Heat Exchangers are best suited for heat sensitive liquids that is those liquids which cannot handle high temperatures, for example, food products or pharmaceuticals, this is because of the low temperature at the interface between the liquid and heat transfer surface.

Statement 1: Scraping improves heat transfer co-efficient by 5 times in case of non-Newtonian fluids. Statement 2: In food industry, major physical changes to food items when they’re processed, take place like transformation from Newtonian to Non-Newtonian fluids. Hence, scraped surface heat exchangers are very beneficial.
The important design and operating considerations for Extended-Surface Compact Heat Exchangers are: (1) Both fluids may have high or low heat transfer coefficients (2) As the tubes are very narrow (low DH), the fluid used should not be corrosive as effective cleaning of tubes is not possible. (3) The fluid pressure drop calculation is important as a regulatory method to ensure long life of the tubes. (4) Unlike shell and tube type heat exchangers, these are limited when it comes to operating pressure and temperature.
Statement 1: For non-Newtonian fluids, another term called apparent viscosity is used as their viscosity changes with the change in the shear rate. Statement 2: For non-Newtonian fluids, between the transition region, the power number for non-Newtonian fluids is slightly higher than that for Newtonian fluids.
