Wrong! Problem 15: The tank shown is filled with salt water (specific weight 64 lb/ft) to a depth of 12 ft. The pressure exerted by the water on the bottom of the tank above atmospheric pressure is 12 ft 5 ft 2 ft □ 640 lb/ft, □ 64 lb/ft2 □ 120 lb/ft2 □768 lb/ft? □None of above
A closed tank is filled with water and has a 4-ft-diameter
hemispherical dome as shown in the figure below. A U-tube manometer
is connected to the tank. Determine the vertical force of the water
on the dome if the differential manometer reading is 7 ft and the
air pressure at the upper end of the manometer is 13.6 psi.
Setting up the manometer equation, I found the pressure in the
closed tank to be 2894.4 lb/ft^2, but when doing the...
A closed tank is filled with gasoline at 60 °F. The tank is pressurized and the pressure at the top of the tank is 10 psi. If the tank is 10 feet tall, what is the pressure at the bottom of the tank? Express your answer in terms of absolute and gage pressure.
1). A large tank is partly filled with water, the air space above being under pressure. A 2” hose connected to the tank discharges on the roof of a building 50 ft above the level in the tank. The friction loss (head) is 18 ft. What air pressure must be maintained in the tank to deliver 0.436 cfs on the roof? Ans. 32.1 psi. 2). If the tank in Q1 is open to the atmosphere, what mechanical power must be...
A scuba diver whose 12L tank is filled with air at a pressure of 150atm at a depth of 15m where the water pressure is 2.5atm. If she uses 30L of air per minute, the same pressure as the water pressure, how long can she stay at that depth? Please show work
Q3: A manometer connected to a tank which is filled with air, and partially with oil having specific gravity of (0.8), as shown in figure (3). Calculate: a) The pressure at the gauge (level 5) in m.oil. b) The absolute pressure at pressure gauge in (m.oil) if the atmospheric pressure is 75cm.Hg. Air 0.8m 3 Pressure gauge 3m Oil S=0.8 Mercury (S=13.6) 15 Figure 1).

An automobile tire is filled with air at a pressure of 44 lb/in2 at 20 °C. The temperature drops to -5 °C. What is the new tire pressure in lb/in2, assuming the volume of the tire does not change? Some students calculate a pressure of 0-is this correct? If not, what mistakes might they have made to obtain a pressure of 0 in their calculation? 1.
A closed tank is filled with water and has a 4-ft-diameter
hemispherical dome as shown in Fig. P2.129. A U-tube manometer is
connected to the tank. Determine the vertical force of the water on
the dome if the differential manometer reading is 7 ft and the air
pressure at the upper end of the manometer is 13.4 psi.
3. (10 points) A U-tube manometer (manometer fluid SG = 3.05) is connected to a closed tank containing a storage liquid as shown in the figure below. The air pressure in the tank is 2.50 psig and the liquid in the tank is oil (SG = 0.865). The pressure at point A is 4.00 psig and x 2.0 ft. Determine: a) the depth of oil, z (ft), and b) the differential reading, h (ft), on the manometer. Open Air kd...
