Q.5 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 (? = 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: i) evaporator capacity,
ii) evaporator economy, iii) The area of heating surface required. Use 1 kcal = 4186 J.

Q.5 Data for pressure vessel are given below:
? Capacity : 10000 L (cylindrical portion only), Operating pressure = 10kg f/cm2
? f = 980kg/cm2, Density of steel = 7.7gm/cc , J = 0.85
? Torspherical heads are provided at both sides.
? For torispherical head, Rc = 10% excess of I.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.
