1. The LMTD profile for evaporator and condenser, what type of flow arrangement will be better co-current or counter-current
2. The length of two thermometers are same, yet they give different temperature scales
3. In an air cooler, if the temperature of air is 30°C, and temperature of water is 30°C, then will the temperature of air will decrease or not. and if the temperature decreases, why?
4. Biot number is defined as hd/k and Nusselt no is hd/k, then why there is a need of two different names?
5. The fin temperature depends on a parameter m = (hp/kA)^0.5, the higher or lower value should be taken for a high efficient fin
6. Difference between efficiency and effectiveness
