An aqueous solution is to be pumped from a storage tank which is open to the atmosphere, i.e.(it operates at 1 atm), to a flash unit which operates at an unknown pressure with the help of a pump operating with a head of 45m. The solution flows at a volumetric flowrate of 105m3/hr through commercial steel piping with a diameter of 18cm. It overcomes flow obstructions listed in Table 1 , before entering the flash unit at an entry point 9m below the exit point of the storage tank (see Figure 1). The length of the straight pipe is 16m and the value of for a commercial steel pipe is 0.045mm. Assume that the viscosity and density of the solution at the prevailing conditions are 0.0005Pa.s and 995(kg/m3) respectively. Table 1: Minor losses through piping system Figure 1: Schematic illustration of a solution being pumped from the storage tank to the flash unit. 1.1. Determine the velocity of the aqueous solution as it enters the system. (7) 1.2. Determine the Reynolds number. (5) 1.3. Determine the total frictional loss in the system (the sum of both minor and major losses). 1.4. Determine the pressure at which the flash unit operates, i.e. (P2). (6)
