1) Explain the relationship between absolute pressure and depth with provide mathematical equations ) 11) (5 marks) If the relationship between absolute pressure (20 kPa -250 kPa) and depth 2.04 m - 25.49 m). What should be the output (volts) the sensor on 5 m and 15 m depth. (7 marks) [25 Marks] ) The MPX4250A/MPXA 4250A series Manifold Absolute Pressure (MAP) sensor for engne control is designed to sense absolute ar pressure within the mtake manifold. This measurement can be used to measure a depth. Pressure sensor used as underwater depth sensor measurement from Famell as shown in Figure Q3 () 1).
