- You are preparing a spaghetti dinner for guests when you
realize that your heat transfer training can be used to answer some
fundamental questions about the process. The pot you are using
holds four liters of water. The atmospheric pressure is 101 kPa.
When on its high setting, the electric stove heating unit consumes
1.8 kW of electrical power of which 20% is transferred to the
surroundings, rather than to the water. The pot is made of 4 mm
thick polished AISI 304 stainless steel and it has a diameter of
0.25 m. The burner diameter is also 0.25 m.
a.) How much time is required to heat
the water from 15 ◦C to its boiling temperature?
b.) What are the temperatures of the outside and inside surfaces
of the bottom of pot while the water is boiling?
