Question Details:

molten solder droplets of diameter 130μm are ejected at a velocityμ of 2 m/s at initial temperatur of 225 celcius into gaseous nitrogen that is 30 celcius and moves slightly to atmospheric pressure. ρ=8230 kg/m^3, c=240 J/kg, k=38 W/mK, h_sf=42 kJ/kg, and the melting temperature is 183 celcius. How do you find the terminal velocity of the particles and distance the particles have traveled when they become completely solidified?
