Discuss the below in detail:
Q: The front door of a dishwasher of width 580 mm has a vertical air vent that is 500 mm in height with a20-mm spacing between the inner tub operating at 52°C and an outer plate that is thermally insulated.
(a) Determine the heat loss from the tub surface when the ambient air is 27°C.
(b) A change in the design of the door provides the opportunity to increase or decrease the 20-rnm spacing by 10 mm. What recommendations would you offer with regard to how the change in spacing will alter heat losses?
