Problem 1:Apply the grid method to each situation.a. If pressure is 8 inches of water (vacuum), what is gage pressure in kPa?b. If the pressure is 120 kPa abs, what is the gage pressure in psi?c. If gage pressure is 0.5 bar, what is absolute pressure in psi?d. If a person's blood pressure is 120 mm Hg, what is their blood pressure in kPa abs?Problem 2:The Crosby gage tester shown in the figure is used to calibrate or to test pressure gages. When the weights and the piston together weigh 140 N, the gage being tested indicates 200 kPa. If the piston diameter is 30 mm, what percentage of error exists in the gage?
