    I have given iocl exam as diploma in chemical engineering .In technical section some question i have remembered are:
    1.the thermal conductivity of a gas:
    i) increases with increasing temp.
    2.relation between stanton no. peclet no. and nusselt no.
    i)nussult no. / peclet no. = stanton no.
    3.which of following heat exchangers is used for chilling oil to be dewaxed?
    i)double puipe heat exchanger
    4. the purpose of steam trap is
    i) to remove condensate and inert gases
    5: steam economy of triple effect evaporator is
    i)>1
    6: Duhring rule is useful in solving problems on
    i) evaporation
    7:dry ice is
    i) solid carbon dioxide
    8:glass is
    i) a super cooled liquid
    9:temporary hardness of water may be removed by adding
    i) calcium hydroxide
    10: carbohydrates are the organic compound of
    i) carbon hydrogen oxygen
    11:vinyl chloride has the formula
    i) CH2=CHCL
    12:the temp. of water cooled in cooling tawer is
    i) always less than the wet bulb temp. of entering air
    and 2-3 question was on kinematic viscosity like dimension of kinematic viscosity and 2-3 was on reflux ratio from distillation, and one question was on pump on n.p.s.h. don't remember that question exactly but mostly question of that paper was from the book of objective type q&a in chemical engineering by Dr Ram Prasad.
