Problems Description :
In all the following problems simply enter all the information
requested and press the calculate button and results will be
calculated each situation.
Changing Volume, at constant pressure, W
This problem relates to a item that has a changing volume at
constant pressure. I.e. a balloon being filled with air, the balloons
volume is changing. The amount of work done to achieve the final
volume is calculated.
Piston, changing Volume, at constant pressure
This problem involves changing volume at constant pressure and
includes forces acting in the situation, which affects the amount of
work required to create the change in volume.
Work, Volume & Pressure Change, W
Calculates the work due to expansion of the system with changing
volume and internal pressure.
Work, Compressor
Calculates the cycle time, power of the fluid and compressor for
this compressor problem/situation.
Heat Temperature Rise, Q
Calculation of heat changes, when a vessel is heated and a fluid
is also present. This situation considers sensible heat and latent
heat changes involved within the system. The calculations allow for
vapourization of the fluid.
Heat Flow, example 1
This refers to the amount of a substance i.e. coal must be burnt
to raise the temperature of a fluid. The calculation considers the
efficiency of the combustion process.
Heat Flow, example 2
Allows for the calculation of heat inputs and losses, temperature
and internal energy changes in a closed system vessel, containing a
fluid being mixed by a stirrer. Assuming no phase change occurs and
it is a closed system.
Heat Flow, example 3
Calculates the heat changes of the system when a substance i.e.
Ice melts within a fluid i.e. water.
Sensible & latent heat changes are calculated and the
equilibrium temperature of the system is solved for.
Bomb Calorimeter

calorimeter experiment.
Bomb Calorimeter - 1
Calculates the heat, system and energy changes of a bomb
calorimeter experiment.
Gas Calorimeter
