a) 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? b) 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. c) Derive the appropriate energy balance for this transient analysis.

hnen't For 1 mole of a gas, the van der Waals equation is where R is the gas constant (0.0821 L atm K mol ') and 7 is the Kelvin temperature 1The constants a and h are constants particular to a given gas and correct for the attractive forces between gas molecules, and for the volume occupied by the gas molecules, respectively. For methane (CH), the constants are a 2.253 L'atm and b4.278 x 10 L. Using the rearranged form of the van der Waals equation RT V -b v? calculate the pressure of 1 mole of methane as a function of container volume 0°C (273 K) at suitable volumes from 22.4 L to 0.05 L.

To ensure a tight fit, the aluminum rivet used in airplane construction are made slightly larger than the rivet holes and cooled by dry ice (solid CO2) before being driven. If the diameter of a hole is 0.500 cm, what should be the diameter of a rive at 20 degree Celsius if its diameter is equal that of a hole when the rivet is cooled to -78 degree Celsius, the temperature of dry ice? Assume the coefficient of expansion to remain constant. (Given and solutions)
