Two streams of water are poured in a tank. Choose the base method as STEAMNBS. The first stream is flowing at 18000 kg/hr (25^oC , 1 atm) and the other at 10000 kg/hr (333 K, 1 atm). The outlet stream from the tank is then passed through a pump having a discharge pressure of 14 atm and a suction area of 507 mm2. Take pump and driver efficiencies as 0.85 and 0.9, respectively. The water is then transported to another tank via a 1500 m long pipe (Material-Carbon steel, Schedule No.- 40, Nominal Diameter- 6 inch), having 4 Gate Valves, 2 Buttery Valves, 12 large 90^o elbows and 20 straight tees. The temperature profile is linear inside the pipe with the outlet temperature as 20^oC . The pipe connection type is FLANGE WELDED and the pipe rise is 0.2 m. A single liquid phase is assumed prevailing inside the pipe. Choose the maximum number of iterations for FLASH OPTIONS for the pipe as 60. Change the default convergence method SQP to COMPLEX from the "Convergence-Options-Defaults-Default Method" tab. Write a Fortran code and find the optimum diameter D for which the given objective function will be minimum, by varying the inner diameter of the pipe from 250 mm to 300 mm, with a step size of 0.5 mm. The objective function (f) is f= 1000D + 10^17/D^5 where D is in mm. Answer the following questions with accuracy up to three digits after the decimal point.
