Question 2 A heat exchanger with a square pitch is designed to cool the shell side fluid which has a mass flowrate of 44.088x 10³ lbm/hr. All the important characteristics of the shell side fluid and the heat exchanger are provided in table 1. Table 1 Do [mm] 15 Ds [mm] 400 +[p] 3.1 p [lbm/m³] 1984.16 Pt 0.01875m LB 0.16m 1cp = 0.001Pa.s; 1Pa = 1.01325 x 10-5bar; 1lbm=0.453592kg; 2.1. Determine what the length the heat exchanger needs to be in meters for a shell side pressure drop of 0.0498 bar. (10) 2 2.2. If the mass flowrate, the fluid density, and the heat exchanger were to remain unchanged and the pressure drop changed to 5.5 kPa, what would be the viscosity of the shell side fluid near the walls?
