elevation & kinetic energy

elevation & pressure

kinetic energy & pressure

none of these

[#]

The co-efficient of discharge of an orificemeter is a function of

Reynolds number at the orifice.

ratio of orifice dia to pipe dia.

Pick out the wrong statement.

Kraft method of pulp manufacture can process all types of fibrous raw materials.

Digestion time for bagasse is less than that for wood base materials.

Both temperature and pressure in the digestor is less in case of the sulphite method as compared to that in the sulphate method.

[#]

Process conditions in fermentator used for production of penicillin is

25°C, 2 atm.

50°C, l0 atm.

30°C, 200 mm Hg (absolute).

90°C, 45 atm.

[#]

The reason for preferring packed towers over plate towers in distillation practice is that the packed tower operation gives

low pressure drop and high hold up.

high pressure drop and low hold up.

low pressure drop and low hold up.

high pressure drop and high hold up.

[#]

10.

When acetone is added in a two layer mixture of methyl isobutyl ketone and water at 30°C, the acetone distributes between the two layers and the composition of the layer follows two solubility curves. For this system,

as the acetone concentration increases, the solubility curves approach each other.

both the phases become identical at a particular common point on both the solubility curves called the plait point.

the distribution curve which is a plot between x (acetone concentration in one phase) and y (acetone concentration in other phase) is analogous to x-y curve used in distillation and absorption terminates on the x = y diagonal at the concentration of the plait point.

all (a), (b) and (c).
