6. 1. State the various types of agitators used in the reactor. [03]
   2. Describe Mc Cabe Thiele method for Distillation. [04]
7. 1. A single effect evaporator is to be designed to concentrate 9000 kg/hr of a solution from 12% to 20% solids. Feed enters at 25 °C. Saturated steam at 110 °C (latent heat = 540 kcal/kg) is available. The condensate leaves at the condensing temperature. Saturation temperature of vapor to the condenser is 400C (A = 580 kcal/kg). Specific heat of all solutions may be taken as 1 kcal/kg®C. Boiling point rise is 5°C. The evaporator has an overall heat transfer coefficient of 1900 kcal/hr.m2.°C. Calculate: 1) evaporator capacity, i1) evaporator economy, iii) The area of heating surface required. Use 1 kcal = 4186 J. [14]

      OR
      Data for pressure vessel are given below:
      Capacity : 10000 L (cylindrical portion only), Operating pressure = 10kg f/cm2
      f=980kg/cm?2, Density of steel = 7.7gm/cc , J = 0.85
      Torspherical heads are provided at both sides.
      

      --- Content provided by​ FirstRanker.com ---

      For torispherical head, Rc = 10% excess of [.D., R1 = 10% of Rc
      Taking L/D = 5, calculate and suggest the plate thickness of shell. Also calculate the thickness of torispherical head and total weight of shell with heads.
