151
Q

In free convection heat transfer transition from laminar to turbulent flow is governed by the critical value of the:

A

Prandtl number, Grashoff’s number

152
Q

When a system deviates infinitesimally from equilibrium at every instant of its state, it is undergoing.

A

Quasi-steady process

153
Q

The condition of refrigerant as it leaves the compressor in a vapor compression system.

A

Superheated vapor

154
Q

The pressure at the outlet of a refrigerant compressor is called:

A

Discharge pressure

155
Q

For most refrigerants, compressed liquid tables are not commonly available. One reason for the lack of
compressed liquid data is the relative independence of compressed liquid with pressure is very mild. A general
approximation is to treat compressed liquid as:

A

Saturated liquid

156
Q

This states that the work required for crushing a given mass of material is constant for the same reduction ratio,
that is, the ratio of the initial particle size to the final particle size.

A

Kick’s law

157
Q

This is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas.

A

Spray drying

158
Q

This is an operation in which the constituents of a liquid mixture are separated using thermal energy.

A

Distillation

159
Q

This unit operation is not intended to kill all microorganisms in the food. Instead, pasteurization aims to achieve
a “log reduction” in the number of viable organisms, reducing their number so they are unlikely to cause disease.

A

Pasteurization

160
Q

The purpose of this unit operation is to destroy all microorganisms present in the food material to prevent its
spoilage and to ensure it is safe for consumption. Microorganisms are destroyed by heat, but the amount of heating
required to kill different organisms varies.

A

Sterilization
