CHEMICAL ENGINEERING Heat and mass
Calculate the cooking time in mins required to raise the temperature at any point half the radius of an cmdiameter dumpling by K The initial temperature of deg C is uniform. The dumpling is heated with flowing steam at K and MPa and velocity of cms The dumpling's heat capacity, density, and thermal conductivity are estimated to be JkgK; kgm; and WmK respectively.
Assume that the Nusselt correlation Perrys Handbook for the shape closest to a dumpling at isothermal surface condition in this problem is valid.
Consider the average temperature of the initial and final temperature of the surface as the constant surface temperature T for the Nusselt calculation.
