A vacuum gage reads 8 in. Hg when the atmospheric pressure 29.0 in. Hg. If the...
Question 3. i. Define absolute pressure, gage pressure and vacuum pressure. ii. If a mercury barometer reads 720 mm Hg. Determine the atmospheric pressure in kPa and psi. (I psi -6.895 kPa. Density of Hg - 13.56 g/cc). Question 4 i. Define/explain energy, kinetic energy, potential energy and internal energy ii. Explain the contribution/mechanism of internal energy with sketch.
Gage pressure represents the difference between the absolute pressure and the local atmospheric pressure while vacuum represents the difference between the absolute pressure and the gage pressure оо
1. A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 699 mm Hg. Express this pressure in atmospheres, kilopascals, torrs, pounds per square inch, and pascals. Hint: 1 atm = 101.3 kPa = 760 torr = 760 mm Hg = 14.69 psi = 1.013×105 Pa mm Hg atm kPa torr psi Pa 699 2. An automobile tire is inflated to a pressure of 29.2 psi. Express this pressure in atmospheres, kilopascals, inches Hg,...
1-47 A vacuum gage connected to a chamber reads 35 kPa at a location where the atmospheric pressure is 92 kPa. Deter- mine the absolute pressure in the chamber.
Part Description Which is true? 1. Absolute pressure-atmospheric pressure - gage pressure A. 2. Absolute pressure-atmospheric pressure + gage pressure If we assume Standard Temperature and Pressure (called "STP") the surface of the Tennessee River is at a gage pressure of 0 psi. What is the gage pressure 10 feet below the B. surface of the Tennessee River? 1. (62.4 lb/ft(10 ft) 2. (62.4 lb/ft3)(32.2 ft/s2)(10 ft)
8. Show that the pressure due to 760 mm of mercury (Hg) is equal to 101kN/m². The specific gravity of Hg is 13.6. (4) 10 Determine the absolute pressure at a depth of 20 ft below the free surface of a body of water (Assume density of water is 62.4 lbm/ft) (4) ha
The vacuum pressure of a condenser is given to be 22 kPa. What is the gage and absolute pressure in kPa? Local atmospheric pressure is 758 mmHg.
Q3) An inclined manometer tube is connected to two closed tanks as shown in the figure below where !-210 cm. A gage was used to measure the pressure at the center of tank A and the reading was 60 kPa. A barometer locates near the tanks reads 72 cm of mercury. Specific weight of water is 9.81 kN/m3 and specific gravity (SG) of mercury is 13.6. a) Find the gage pressure in the center of tank B. b) Find the...
8. The figure shows a tank within a tank, each containing air. Pressure gage A, which indicates pressure inside tank A, is located inside tank B and reads 5 psig (vacuum). The U-tube Pa 14.7 psia Tank B manometer connected to tank B contains water with a column length of 10 in. Using the data shown on the figure, determine the absolute pressure of the air inside tank B and inside tank A, both in psia. The atmospheric pressure surrounding...
A pressure gage at elevation 4.8m on the side of a storage tank containing oil reads 34.7 kPa. Another gage at elevation 2.2m reads 57.5kPa. Compute the specificweight, density, and specific gravity of the oil?
