Question

1. A syringe has initial air gauge pressure of 0 kPa and volume of 60 cc. Find the gauge pressure when the syringe’s air volume is reduced to 55 cc

2. A solid-state (SS) pressure sensor has linear voltage measuring function ?_??? = ??, where K =40mV/kPa within full pressure measuring range of 0 kPa to 5 kPa. The pressure sensor is connected to a tunnel to measure the liquid pressure p that is given as ? = 0.5?? 2 , where ? is the liquid density in kg/m3 and ? is the liquid speed in m/s. If the liquid is water with density of 10 3 kg/m3 , find the corresponding full measuring ranges of speed and voltage measurement that the pressure sensor is able to measure.
