The specific gravities of oil and mercury are given to be 0.
Then, ternodinamica weight on the moon will be lbf Assumptions 1 All the liquids are incompressible. The work output of a device is maximum and the work input to a device is minimum when quasi-equilibrium processes are used instead of nonquasi-equilibrium processes.

For a given mercury-level difference between the two columns, the absolute pressure in the duct is to be determined. The pressure exerted on the surface of the diver by water is to be determined.
This fatal level temperature change of body temperature is to be expressed in F, K, and R. Limited distribution permitted only to teachers and educators for course Properties The specific gravities are given to be 1.
Analysis The drag force depends on a dimensionless drag coefficient, the edicipn density, the car velocity, termodunamica the frontal area.
Parte 5 de 5 5tx The specific gravities of oil, mercury, and gasoline are given to be 0. Also note that brackets can also denote comments – but these comments do not appear in the formatted equations window. The pressure difference between the two pipelines is to be determined.
Limited distribution permitted only to teachers and educators for course 4. The water column height in one arm termodinamic the ratio of the heights of the two fluids in 5fa other arm are given. Assumptions 1 The diameter given is the outer diameter of the duct or, the thickness of the duct material is negligible.
Similar problems and their solutions can be obtained easily by modifying numerical values. Assumptions The weight of the cage and the ropes of the balloon is negligible. For a constant volume of blood to be discharged by the heart, the blood pressure must increase to overcome the increased resistance to flow. For a given pressure drop and brine level change, the area ratio is to ecicion determined. Assumptions The density of air is constant throughout the room.
The absolute pressure at the center of the pipe is to be determined.
The height at which the weight of a body will decrease by 0. The system can also interact with the surroundings by exchanging heat and work across its control boundary.
Assumptions The variation of the density edjcion the liquid with depth is negligible. This cooling process is then an isobaric process. The mass of the petcock is to be determined. The local atmospheric pressure in that city is to be determined.

Limited distribution permitted only to teachers and educators for course 7. As the water cools, its pressure remains fixed. Accounting for this variation, the weights of a body at different locations are to be determined.
Limited distribution permitted only to teachers and educators for course 6.
Discussion Note that sometimes the use of specific gravity offers great convenience in the solution of problems that involve several fluids. It is the gage pressure that doubles when the depth is doubled.
Analysis The atmospheric or barometric pressure can be expressed as 30 kPa Pabs kPa0. When there is flow, the pressure drop in the tube due to friction should also be considered. Assumptions Gasoline is an incompressible substance and the flow rate is constant.
Analysis Applying Newton’s second law to the weight force gives lbm5.

Termodinanica on unit considerations, a proportionality relation is to be obtained for the mass flow rate of air through the blades.
It violates the second law of thermodynamics. For a specified reading 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. That is, multiplying a temperature termofinamica in K by 1. If the diagram window is hidden, then all of the input must come from the equations window. For the given specific gravities and fluid column heights, the gage pressure at A edocion the height of a mercury column that would create the same pressure at A are to be determined.
We let the height of water and oil in the right arm to be hw2 and ha, respectively. Therefore, its effect on the pressure difference between the two pipes is negligible. Therefore, the differential height of the mercury column must be Limited distribution permitted only to teachers and educators for course 9. The amount of electric energy used in kWh and kJ are to be determined. Hence, the weight is an extensive property. Discussion Note that the values of dimensionless constants of proportionality cannot be determined with this approach.
The amount of heat loss from the apple per F drop in its temperature is a 1.
