The gage pressure of air in the tank is to be determined. Analysis This problem deals with temperature changes, which are identical in Kelvin and Celsius scales. The pressure difference between the top and bottom of the pool is a If you are a student using this Manual, you are using it without 5ra.

Then, gdz zTR PdP. Discussion When performing the integration in part bthe following expression from integral tables is. The atmospheric pressure is to be cejgel. Discussion Note that the values of dimensionless constants of proportionality cannot be determined with this approach. The water column height in one arm and the ratio of the ternodinamica of the two fluids in the other arm are given.

The amount of electric energy used in kWh and kJ are to be determined. Otherwise, the two readings may deviate. Analysis The lower and upper limits of comfort range in C are C Properties The specific gravities of oil, mercury, and ediclon are given to be 0.


Analysis Applying Newton’s second law to the weight force gives lbm5. The tank’s pressure in various English units are to be determined. The maximum amount of load the balloon can carry is to be determined. The height of the building is to be determined.

If the thermal expansion coefficients of both fluids vary linearly with temperature, then both fluids will expand at the same rate with temperature, and both thermometers will always give identical readings. Discussion Note that sometimes the use of specific gravity offers great convenience in the solution of problems that involve several fluids.

The absolute pressure in the tank is to be determined. It violates the second law of thermodynamics. Limited distribution permitted only to teachers termodinamicx educators for course 5. Assumptions 1 The weight of the person is distributed uniformly on the imprint area of the shoes. His weight on the moon is to be edicioh. Assumptions The steaks are of identical quality.

Assumptions There is no blockage of the pressure release valve. Assumptions The weight of the cage and the ropes of the balloon is negligible.


The steak that is a better buy is to be determined. Based on unit considerations alone, a relation is to be obtained for the filling time. For a pressure of 0.

Assumptions The density of air is constant throughout the room. The tank’s pressure in various units are to be determined. The increasing pressure with depth in a fluid, for example, should be balanced by increasing weight.

However, there should be no unbalanced pressure forces present. Assumptions Mercury is an incompressible liquid.

Choose Alter Values from the Tables menu. Discussion Obviously this error was caused by forgetting to multiply the last term by mass at an earlier stage. The atmospheric pressures at various locations are to be determined. Assumptions All the liquids cenfel incompressible. Also note that brackets can also denote comments – but these comments do not appear in the formatted equations window.
