7.- To measure the pressure of a gas we use as a manometer a U-shaped tube which contains mercury. The difference in height in the tubes of the manometer is 40 cm. Calculate the value of the manometric pressure of the gas. The density of mercury is 13600 kg/m3.

N.B. Do the exercise in your notebook and carry out the calculations using SI units.
