Please make the calculations

3. A pipe is coated on the inside with naphthalene and has an inside diameter of 2.5cm and a length of 1.1m. Air at 318K and 101.32kPa flows through this pipe at a velocity of 10 m/s. Calculate the molar flux of naphthalene (kmol/m2s) which evaporates to air and mass transfer coefficients (kc,ky) at process conditions. Dnapht-air=6.92106m2/s;air=1.932105 Pa.s; air=1.114kg/m3;Pnapht=74kPa at process conditions. Flow inside the pipe Sh=0.023Re0.83Sc0.33;40003000 Flow outside the pipe (perpendicular to the cylinder axis) JD=0.06Re0.487;50
