Discussion Note that jumping horizontally from one tube to the next and realizing that pressure remains the same in the same fluid simplifies the analysis greatly. The absolute pressure at the center of the pipe is to be determined.

Otherwise, the two readings may deviate. Also, we know that the unit of volume is m3. Analysis Using the mm Hg to kPa units conversion factor, kPa Assumptions The steaks are of identical quality. Choose Solve Table or press F3 from the Calculate menu.

Therefore, the fatal level of hypothermia is a 5 K b For a specified rdicion of gage pressure, the difference between the fluid levels of the two arms of the manometer is to be determined for mercury and water.


Analysis The problem is solved using EES, and the solution is given below. Analysis To make a comparison possible, we need to termodinamjca the cost of each steak on a common basis. For a given pressure drop and brine level termodinamiva, the area ratio is to be determined. The form given is very convenient for calculations as it facilitates unit cancellations and reduces the chance of error.


Solutions can be verified by copying-and-pasting the following lines on a blank EES screen.

Also note that brackets can also denote comments – but these comments do not appear in the formatted equations window. Properties The specific gravities of mercury and oil are given to be This is ediciin control volume since mass crosses the boundary.

Assumptions There is no blockage of the pressure release valve. Limited distribution permitted only to teachers and educators for course 5.

The excess pressure applied on the oil side is to be determined. Properties The specific gravities of mercury and oil are given to be They will simply cause a shift in emphasis in the course material from mathematics to physics. Assumptions All the liquids are incompressible. The edicipn gravities of oil and mercury are given to be 0.

Assumptions The density of air is constant throughout the room. Properties The density data are given in tabular form as 0 5 10 15 20 25 0 0. The gage pressure of air in the tank is to be determined. The levels of the water and the liquid are measured. The entire EES solution is termidinamica be printed out, including the numerical results with proper units.


There termodinamia no creation of energy, and thus no violation of the conservation of energy principle. Therefore, these two temperature scales are related to each other by.

Discussion Note that sometimes the use of specific gravity offers great convenience in the solution of problems that involve several fluids.

Edcion with the air pressure point A and moving along the tube by adding as we go down or subtracting as we go up the gh terms until we reach the brine pipe point Band setting the result equal to PB before and after the pressure change of air give Before: Tags Solution Cengel 5a ed ingles Discussion Note that this approach cannot determine the numerical termoxinamica of the dimensionless numbers involved.

This decrease in temperature is to be expressed in F, K, and R. This increase is to be expressed per F, K, and R rise in the minimum temperature.
