Poached eggs are cooked in bath of boiling water at 100°C. Over time they reach thermal equilibrium with the bath. They are then
quickly removed from the boiling water and placed in ice water at 0°C to stop the cooking process. Assume the eggs are perfect spheres with a diameter of 4 cm, a thermal conductivity of 2 W/mK, and a thermal diffusivity of 1e^-6 m^2/s. It is very important that the temperature within the eggs remains spatially uniform during the cooling process.
a) Find the maximum heat transfer coefficient of the ice bath that is allowable.b) Assuming the heat transfer coefficient found in (a) is used. Find the eggs should remain in the ice bath to cool them to 75°C.

Answer:
hello your question lacks the required question attached below is the missing diagram
Forces in GJ = -4.4444 i.e. 4.4444 tons
Forces in IG = 15.382 tons ( T )
Explanation:
Forces in GJ = -4.4444 i.e. 4.4444 tons
Forces in IG = 15.382 tons ( T )
attached below is the detailed solution
Answer:
D = 0.060732 in
Explanation:
given data
sp. wt. = 500 lb/ft³
diameter = 0.036 in
solution
we get here maximum diameter of rod that is express as
D = ......................1
here surface tension of water at 60⁰f = 5.03 ×
lb/ft and y = 500 lb/ft³
so put here value and we will get
D =
D = 0.005061 ft
D = 0.060732 in
