What is separating and throttling calorimeter?

Correspondingly, what is a throttling calorimeter?

An instrument utilizing the principle ofconstantenthalpy expansion for the measurement of the moisturecontent ofsteam; steam drawn from a steampipe through samplingnozzles entersthe calorimeter through a throttlingorifice andmoves into a well-insulated expansion chamber in whichitstemperature is measured.

Similarly, when wet steam flows through a throttle valve? When wet steam flows through a throttle valveandremains wet at exit,then what about temp and qualityofsteam increase or decrease? The function ofthrottlevalve is to decrease the pressure. Or say madesudden pressuredrop.

Also asked, why is steam calorimeter used?

A separating and throttling calorimeter canbeused to determine the dryness fraction of steam inasystem. The steam is then passed through a throttlewhichdrops the pressure down to atmospheric, whereupon thesteamis condensed and collected for weighing.

What is meant by throttling process?

A throttling process is defined asaprocess in which there is no change in enthalpy fromstateone to state two, h1 = h2; no work is done, W = 0; andtheprocess is adiabatic, Q = 0. An example of athrottlingprocess is an ideal gas flowing through a valve inmidposition.
