Discuss
Answer: (c).dT/dt= α (d²T)/ (dx)²
Q13.
For a copper pipe, k = 0.3534, temperature difference = 60, B = 0.0125 and A = 850. What is the value of q?
Discuss
Answer: (b).1442 kW
Discuss
Answer: (d).All of the mentioned
Q15.
__________ is when nucleate boiling transforms to film boiling.
Discuss
Answer: (b).Leiden frost point
Q16.
Statement 1: Nucleate Boiling is when a layer of film is formed in the beginning.
Statement 2: Boiling starts with the bottom layer which heats up, becomes light and goes up. That way everything becomes hot and there is not temperature difference and hence no heat transfer.
Discuss
Answer: (d).False, True
Q17.
Statement 1: When heat transfer takes between a solid surface and a fluid, an insulating film layer is formed. More is the agitation; more is the thickness of the film.
Statement 2: Within the film, the temperature varies from the wall to the temperature of the bulk.
Discuss
Answer: (d).False, True
Q18.
Statement 1: Nₚᵣ= (Cₚμ)/k
Statement 2: If Nₚᵣ is lesser than 1, Thermal Boundary layer is thinner than Hydrodynamic Boundary layer.
Discuss
Answer: (a).True, False
Discuss
Answer: (d).All of the mentioned
Q20.
Statement 1: hd/k is _____
Statement 2: _____ is the ratio of convective heat transfer to conductive heat transfer.
Discuss
Answer: (b).Nussel number, Nussel number
