For a design flow rate of 0.050 m 3/s, and average water temperature of 8oC. design a flocculation tank by providing the following for the first two compartments only: 1. Water power input in kW 2. Tank dimensions in m 3. Diameter of the impeller in m 4. Rotational speed of impeller in rpm Use the following assumptions: 1. Number of tanks

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
