How is heat transferred to the burrito if it is heated in a microwave oven? How about when it is toasted in an oven?
Write the energy balance equation for the burrito in the toaster oven assuming the boundary is around just the burrito.
Write the energy balance equation assuming the boundary is around the toaster oven/burrito system.
The power supplied to the microwave oven is 900W. The power supplied to the toaster oven is 1250W. The burritos are the same size and composition, start out at the same initial temperature, and reach the same final temperature after heating. The burrito in the toaster oven takes 12min to heat, and the burrito in the microwave takes 2 minutes to heat. What is the relative efficiency of the microwave over the toaster oven?
Microwave ovens lose energy in converting electrical work to microwaves, and their conversion efficiencies are approx. 0.5. Assuming an efficiency of 0.5 for the microwave, what is the efficiency of the toaster oven?
Water ?ows in a rectangular conduit 12-cm high and 60-cm wide having a maximum velocity of 20 m=s with the pro?les shown in Fig. 4.16. Assume the pro?le exists across the entire cross section with negligible end effects. Calculate the mass ?ux, th..
A simple fundamental equation, which exhibits some of the thermodynamic properties of solids is: U(s, v) = Aeb(v-v_0)^2S4/3eS/3R. Show that the thermal expansion coefficient of the solid vanishes at 0 pressure
Is this expression for H an approximation to the fundamental relation, or is it an equation of state. Explain your answer for credit.
