Question

Describe working principle of throttling calorimeter with neat sketch and also state the limitations.

Answer 1

Answer:

Explanation:

An instrument utilizing the principle of constant enthalpy expansion for the measurement of the moisture content of steam; steam drawn from a steampipe through sampling nozzles enters the calorimeter through a throttling orifice and moves into a well-insulated expansion chamber in which its temperature is measured.

Answer 2

Principle: The principle of the throttling calorimeter is to throttle the wet steam so that it becomes superheated. ... The pressure gauge attached to the outer casing and thermometer in inner chamber gives the pressure and temperature of steam after throttling, respectively.
