In this practice, you will apply a quadratic inequality to describe the pressure that can be withstood by moisture indicating sight glasses. You need to solve the equation and find the correct solution. In this application, you will use whole numbers, as pressure can be negative, and as the equipment does not function with decimals. To carry out the practice, you have been given a vacuum pump, a compressor, a control panel, sight glasses, an analog pressure gauge and a digital pressure gauge.
