Which of the following statement(s) about steam calorimeters is/are correct?
O The ideal degrees of superheat of steam passing through throttling calorimeter is 5.5°C
O Typical condition of steam entering a calorimeter is wet-vapor mixture and superheated when exiting
O Electrical calorimeter operates approximately as barrel calorimeter with modifications in some parts.
O If a throttling calorimeter is insufficient, there is a need to measure the pressure and temperature of steam passing through it.
O For a separating calorimeter. series of obstacles are found within the separating charmber which separate liquid particles from
vapor.
O Actual quality of the steam is equal to the computed value of dryness fraction, neglecting lossies
O For separating and throttling calorimeter, the quality 2 is greater or higher than quality 1.
