A helix is made of 2-in schedule 40 pipe turned up to 21 giving a diameter of 1.5625 m. The liquid is entering through the coil at a temperature of 45 oC and leaving at 35oC. The average wall tube temperature is given to be 35oC. The volumetric flowrate of 2-propanol entering is .00279 m3/s. Calculate the frictional pressure drop in a straight pipe and the pressure drop in coil.
