Problem #1 A simple barometer can be made in much the same way as a manometer, shown in Fig. 2-1. In the figure, the reservoir initially contains 1 L of air (an ideal gas) t'C and P 101.3 kPa. The diameter of the reservoir is 5 cm, while the diameter of the tube is 0.5 cm. The working fluid is water (p-999 kg/m3). Consider a manometer located in a room at T- 20°C (a) What will the deflection, h, of...

20.) A 10.0 kg mass is attached to the end of a 2.00 m long brass rod, which has a diameter of 1.00 mm and negligible mass. The mass at the end is pulled, stretching the rod slightly, and then released. If the elastic modulus of brass is 9.10 × 1010 N/m2, then the frequency of the resulting oscillations is. ___Hz 19.)

The column of a mercury barometer is calibrated in linear units
(such as inches or millimeters) and thus the air pressure observed
on such a barometer is reported in terms of these linear units.
This measurement of pressure can be converted to other common
pressure units. Some conversion factors are shown here.
1mm Hg = 1torr
1 atm = 760mm Hg
1 atm = 1.01325 bar
