The extra power needed is to be determined for three different termkdinamica. Analysis The work applied to the block to overcome the friction is found by using the work integral, Btu2.

Assumptions The differences in installation costs of different heating systems are not considered. Assuming that the air composition and velocity do not change and that no pressure front motion occurs during the day, the warming process is one of constant pressure i. The effect of frictional losses in a pump is always to convert mechanical energy to an equivalent amount of thermal energy, which results in a slight rise in fluid temperature.

Analysis The lower and upper limits of comfort range in C are C Assumptions The boiler operates at full load while operating.

Note that this pumping process could be accomplished by a C, and by radiation to the surrounding surfaces at 15C. The temperatures of the electrical parts of the monitor are higher than that of termidinamica surrounding air. The total volume and the total internal energy are to be determined.

Teromdinamica 1 The IV fluid is incompressible. Leaded gasoline contains lead that ends up in the exhaust. Shaft Nozzle Vj Analysis Kinetic energy is the only form of harvestable mechanical energy the water jet possesses, and it can be converted to work entirely. The surface temperature of the spacecraft is to be determined when steady conditions are reached.

Assumptions 1 The bubble is treated as a spherical bubble.

Many engineering processes can be approximated as being quasi-equilibrium. Analysis The total yujus energy of water in an upper reservoir relative to water in a lower reservoir is equivalent to the potential energy of water at the free surface of this reservoir relative to free surface of cenvel lower reservoir.

Assumptions 1 Steady operating conditions exist since the ball surface xe the surrounding air and surfaces remain at constant temperatures. The sulfur in the fuel reacts with oxygen to form sulfur dioxide SO2which is an air pollutant. Analysis The required power is determined from kW This increase is to be expressed per F, K, and R rise in the minimum temperature. EES Solution for final result: Analysis It is clear from the problem statement and the figure that the brine pressure is much higher than the air pressure, and when the air pressure drops by 0.

The pressure difference between the top and the bottom of the container is to be determined. Assumptions 1 The flow is steady and termodinamoca. This is known as acid rain.

For a given mercury-level difference between the two columns, the absolute pressure in the duct is to be determined. Differential fluid height against the density is to be vengel, and the results are to be discussed. The number of 5-kW window air conditioning units required is to be determined. The V in the equation is a constant whose value is equal to the numerical value of the velocity in mph. Therefore, its effect on the pressure difference between the two pipes is negligible. The boiling temperature of water in the Kelvin and the Smith scales are Assumptions The two heaters are comparable in all aspects other than the initial cost and efficiency. Assumptions The differences in installation costs of different water heaters are not considered. Assumptions The air pressure in the tank is uniform i.

Assumptions 1 Atmospheric air behaves as an ideal gas.

The average velocity of the air and the conversion efficiency of the turbine are to be determined. The mechanical efficiency of the pump is to be determined. Analysis To make a comparison possible, we need to express the cost of each steak on a common basis. Analysis The plant operates 12 hours a day, and thus currently 6ya lights are on for the entire 12 hour period. This is a closed system since no mass enters or leaves. Assumptions All the liquids are incompressible. As a result, the warm mixture of air and gasoline on top of an open gasoline will most likely settle down instead of rising in a cooler environment C Ice can be made by evacuating the air in a water tank. The voltage of the current source is to be determined, and the process is to be shown on a P-v diagram. The weight of 1 lbm mass in English units is a 1 lbf b 9. Analysis The rate of evaporation of water is H2O Properties The gravitational acceleration g is given to be 9.

Heat transfer from the back surface of the board is negligible. Analysis Weight is proportional to the gravitational acceleration g, and thus the percent reduction in weight is equivalent to the percent reduction in the gravitational acceleration, which is determined from 0.

The temperature of the outer surface is to be determined. If we divide a system into smaller portions, each portion will contain fewer atomic particles than the original system. Analysis The weight of the rock is N
