Liquid hydrocarbon (or organic liquid) is discharged at the rate of 6000 kg/h from a reactor to a storage tank at 50C, shown in Figure 2. The reactor is working at 500 kPa pressure. The density of the liquid hydrocarbon is 920 kg/m3, and viscosity is 0.91 mPa.s or cP. Assume no flashing of the liquid hydrocarbon across the control valve.
