4. Figure shows a tank within a tank, each containing air. Pressure gage A is located inside the tank B and reads 140 kPa. The U-tube manometer connected to tank B contains mercury. Using data on the diagram, determine the absolute pressures inside the tank A and tank B. Tank B Pa- 101 kP. L=20 cm Tank A Gage A Pewr.A14 har Mercury (p13.59 g/cm?) 9.si ms

In the Figure shown, find the Pressure difference between A and B. Given: Specific Gravity of Oil, SGoil = 0.85, Specific Gravity of Mercury, SGmercury = 13.6, Specific Gravity of Kerosene, SGkerosene = 0.81, Specific Weight of Water, Ywater= 9790 N/m², Specific Weight of Air, yair = Also, hi = 20.0 cm, h2 = 14.0 cm, h3 = 10.0 cm, h4= 8.0 cm, h5 = 4.0 cm. 12 N/m³. Show all calculations. Kerosene Air IB A oil hay hi Water Mercury

Fig shows a U-tube differential manometer connecting two pressure pipes at A and B. Pipe A contains a liquid of specific gravity 1.8 under the pressure of 101 kN/m?. The pipe B contains oil of specific gravity 0.6 under the pressure of 219 kN/m2. Find the difference of pressure measured by mercury as fluid filling U-tube in mm. The value of x and y are 2.1 m and 1.2 m respectively. Pa S, X B X- Mercury The Mercury level difference ( h ) in mm

3. The reading of an automobile gage is proportional to the gage pressure at the bottom of the tank as shown. The tank is 32 cm deep. Unit weight of gasoline is 6670 N/m³ and that of air is 11.8 N/m³. Unit weight of water is 9790 N/m³. Vent Air Gasoline Water a. Determine the gage reading when the tank is full of gasoline. b. How many cm of air remains at the top when the gage indicates full and the tank is contaminated with 3 cm of water? c. Determine the pressure at the interface of the gasoline and water when the gage indicates full.
