The U-tube manometer is filled by several fluids as shown. Compute the pressure reading at the manometer if hl=10 cm; h2=25 cm; h3=60 cm, and h4=20 cm. The U-tube is open to the atmospheric pressure. Assume SG for oil 0.78 and for Hg 13.7. Water density is 1,000 kg/m³ and air density is 1.225 kg/m³. Air Oil Pressure gage Open to atmosphere Mercury

Q7 A water manometer is used to measure the pressure in a gas main. The graduated scale reads 260 mm in one limb and 146 mm in the other. Atmospheric pressure is normal. Determine the following (a) the gas pressure in kPa (gauge) (b) the absolute gas pressure

can u solve pls #3

If the PO2 is 100 mm Hg at one barometric pressure (760 mm Hg), what is the approximate PO2 if the pressure is increased to 1,520 mm Hg in a hyperbaric chamber?
