Solution on all other sites including this site are wrong Only attempt if previously not attempted. Answer part a and b A) Among the nondimensional numbers, in free convection, average Nusselt number depends on only Grashof and Prandtl numbers. only Grashof number. Rayleigh number. Reynolds number. B) For ideal gases, the specific heat capacity at constant pressure, thermal conductivity, dynamic viscosity, and Prandtl number are independent of pressure. How will the ratio of thicknesses of velocity boundary layer and thermal boundary layer change if pressure is increased from 1 atm to 5 atm for the flow of an ideal gas over a flat plate? We need to know the actual fluid properties to tell It will remain the same. It will decrease by a factor of 5. It will increase by a factor of 5.

a) First, let's start with the steady-state analysis for the cable. What is the steady-state temperature of the wire surface if this current has been passing through the cable for a long period of time in these underwater conditions? Enter only a numeric value (with no units entered) and express your answer in ∘C. b) Now, let's think about the transient case. Assume that the cable starts at the same uniform temperature as the water and then the electrical current is passed through the cable. We're now interested in the amount of time it takes to heat up. Start by calculating the Biot number for this scenario. Enter only a numeric value (your answer should be unitless). c)
