Question

Draw the P-V diagram to support yotir views. (6 Marks) Identify various pressure gauges used in oil rig applications and explain how they are
used for drilling related decision making process. stion 4 (10 Marks) a. The carburettor of a petrol engine incorporates a venturi with a diameter of 25 mm at the inlet and a diameter of 15mm at the throat is shown in figure 5. If the air velocity at the inlet is 25ms-1 and the atmospheric pressure is 101 kPa. calculate the static pressure at the inlet and throat. Take the density of air to be 1.2 kg m-3. Assume that the carburettor is mounted horizontally.
