Both of these are positive quantities since as the mercury-brine interface drops, the differential eeicion heights for both mercury and brine increase. This is a consequence of the pressure in a fluid remaining constant in the horizontal direction. Properties The densities of air and mercury are given to be 1. Therefore, the independent quantities should be arranged such that we end up with the unit of seconds.

Hence, the weight is an extensive property. 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.

Assumptions The variation of the density of the liquid with depth is negligible.

Starting 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 Ceengel The boiling temperature of water in the Kelvin and the Smith scales are termodinmica Analysis The drag force depends on a dimensionless drag coefficient, the air density, the car velocity, and the frontal area. Analysis The lower termodianmica upper termodinamia of comfort range in C are C The excess pressure applied on the oil side is to be determined.


The system can also interact with the surroundings by exchanging heat and work across its control boundary. The difference between the pressures acting on the head and on the toes is to be determined. The gage pressure in the same liquid at a different depth is to be determined. Therefore, this force must be treated seriously. The height at which the weight of a body will decrease by 0. Analysis To make a comparison possible, we need to express the cost of each steak on a common basis.

Analysis Both fluids are open to the atmosphere.

Assumptions The air pressure in the tank is uniform i. Termodinamica e Sistemas termodinamica. The underscore displays whatever follows as subscripts in the Formatted Equations Window.

This is expected since oil is lighter than water. The entire EES solution is to be printed out, including the numerical results with proper units.

The gage pressure of air in the tank is to be determined. Analysis a The pressure in the duct is above atmospheric pressure since the fluid column on the duct side edocion at a lower level. For the given specific gravities and fluid column heights, the gage pressure at A and the height of a mercury column that would create the same pressure at A are to be determined.

Limited distribution permitted only to teachers and educators for course 8.

The pressure of the gas is to be determined. The pressure exerted on the surface of the diver by water is to be determined. By opening and using this Manual the user agrees to the following restrictions, and if the recipient does not agree to these restrictions, the Manual should be promptly returned unopened to McGraw-Hill: This explains why IV tubes must be placed high to force a fluid into the vein of a patient.

Post on Aug views. Analysis The problem is solved using EES, and the solution is given below. Analysis The power needed for acceleration depends on the mass, velocity change, and time interval. Set values of h to range from 0 to 1 in steps of 0. This Manual may termoddinamica be sold and may not be distributed to or used by any student or other third party.

The height of each fluid in that arm is to be determined. For a given vertical level difference, the gage pressure in the duct and the length of the differential fluid column are to be determined. The local atmospheric pressure and the absolute pressure at the same depth in a different liquid are to be determined.

No csngel use or distribution of this Manual is permitted.

The rate of heat loss is to be expressed per F, K, and R of temperature difference between the indoor and the outdoor temperatures. Analysis The absolute pressure P1 is determined from kPa The mass and weight of the air in the room are to be determined.

Assumptions The gravitational acceleration does not change with altitude.
