Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Blaise Pascal duplicated Torricelli's barometer using a red Bordeaux wine, of density 984 kg/m3, as the working liquid (figure below). A long tube is upside-down, with its closed end in the air and its open end submerged in a tank of wine. A column of wine inside the tube extends from the surface level of the wine outside the tube to nearly the top of the tube. The height of the column is labeled h. The pressure outside the tube is labeled P0, and an arrow below the P0 label points down toward the surface of the tank. (a) What was the height h of the wine column for normal atmospheric pressure? m(b) Would you expect the vacuum above the column to be as good as for mercury? YesNo
A vertical venturimeter carries liquid of relative density 0.8 and has inle. and throat diameters of 150 mm and 75 mm respectively.

A water filled pipe has water flowing at v1= 5.90 m/s in a section of pipe where the diameter is d1= 20.2 cm and the pressure is known to be P1= 7.00×104 N/m2 above atmospheric pressure. If the pipe carries the water 3.5 meters up hill without any change in diameter, what is the new absolute pressure within the pipe? After flowing up the hill described above, the pipe narrows to 80% of its original radius, what will be the new water velocity (v2) in the pipe? What will be the absolute pressure (P3) in the smaller pipe? a. What is the volume flow rate through the smaller pipe?
