The first goal was to observe based off the collected data how pressure relates to temperature when undergoing a phase change; the second goal was to calculate the enthalpy of vaporization of water in order to see how much heat energy was needed to change one mole of liquid into one mole of vapor.
The specific latent heat of vaporization of water, L, is found by a method of mixtures using a set up shown in figure 7.2. Water is boiled in flask F and the steam is introduced into the calorimeter via a vessel V which traps any water. Fig. 7.2.
The ‘system’ is made up of a vacuum pump to reduce pressure, an ice/water cold trap to capture sample vapors, a 3-way stopcock, an isoteniscope to contain your sample, a large empty jar (ballast tank) used to reduce the pressure fluctuations, and an open-end mercury manometer to measure system pressure.
The purpose of this experiment is to calculate the enthalpy of vaporization of water by finding the vapor pressure of water over a range of temperatures. 2 Procedure. In an inverted 10mL graduated cylinder, a sample of air is trapped. The cylinder is submerged in a 1L beaker of water.
2 lut 2011 · The flow pattern in a hydrocyclone is cyclonic. This is induced by tangential injection of the liquid into a cylindrical chamber, which causes the development of a vortex. The chamber has a restricted axial bottom outlet such that all of the liquid in the vortex can not escape via this outlet.
The purpose of the experiment is: To understand what vapour pressure is and how it changes with temperature. To understand the relationship between vapour pressure at a given temperature and boiling temperature at a given pressure. To determine the vapour pressure of a pure liquid at various temperatures.
2 lut 2011 · When a cyclone separator is overloaded, the pressure in the swirl chamber drops so much below that of the pool into which the separated liquid drains that the liquid rises up the down commer and floods the separator.
