In a pharmaceutical plant a reactant (assume with properties of water at 10°C) and flow rate of 200 g/min must be directed through a pipe across a 300 m bridge. There are two options for he pipe: a 1 cm diameter pipe and a 2 cm diameter pipe. 1) Find the average fluid velocity for each pipe 2) Find the Reynolds number for the flow in each pipe 3) Find the pressure drop due to friction losses across the length...

A water treatment plant is processing water at a flow rate of 1.5 m/s using three parallel treatment trains. The detention times for the rapid mix tank, flocculation basin, and rectangular sedimentation basin are 10 sec, 30 min and 60 min, respectively. The velocity gradients for the rapid mix and flocculation tanks are 900 s and 60:40:20 s1, respectively. The viscosity of water is 0.001 Pa-s. (a) Determine the size and power requirements for rapid mix tanks. (b) Determine the...

A water treatment plant is to be designed to supply a daily flow of 35000 m/d. The raw water is taken from a local river that has a turbid water. The main treatment units of this treatment plant are as illustrated in Figure 1: Screen River Water > Sedimentation Coagulation Flocculation Filtration Adsorption Adsor prion > Disinfection Storage Distribution Figure 1: Water treatment plant main unit The design criteria of each treatment unit is as follows: 1. Coagulation tanks (Rapid...

8-C) As shown below water is pumped and sprayed through a nozzle into the atmosphere at 20 m/s at an elevation 10 m above the reservoir surface. The mass flow rate is 40 kg/s and the volumetric flow rate is 0.040 m3/s. The large diameter inlet pipe total length is 50 m. The pump effidency is 65%. The longer smaller diameter pipe leaving the pump is 200 m in total length. The pipes have different diameters as indicated below. The...
