the pressure sensor datasheet, estimate the total uncertainty including nonlinearity. sensitivity (10% of the reading), and resolution of the pressure measurement (in psi) based on the approximate reading from Q2 and a FSO (Full Scale Output) of 5 V./nThis lab will be conducted in your lab groups - You must also collaborate on this pre-lab worksheet. Each team member must contribute to the calculations, and each question should be checked/ verified by at least one other group member. When completed, you must fill in the attributions table below. Each group member is responsible for the whole group's work - all group members will receive the same grade. The pre-lab worksheet is designed to prepare you for the lab class. Upon completing you should be familiar with the lab instructions, the type of calculations required for the analysis, the equipment datasheets, and the overall goal of the lab. Upload a completed version of this worksheet to Canvas before the deadline. Name Манария Signature Cile impe Work carried out Work checked The objective of this lab is to calculate the velocity of a shock wave caused by a disk rupture in a tube. The tube is separated into 2 sections, a high pressure side and a low pressure side, using a mylar disk. Pressurizing the high pressure side with air from the wall feed causes the disk to burst/nsending a shockwave into the low pressure chamber. We can detect these spikes in pressure using 2 piezo electric sensors at set distances along the low pressure side of the tube. Capturing this event using an oscilloscope, we can find the time taken for the shock wave to pass the sensors, so knowing the distance between them, we can calculate the speed of the shock. Below are pictures of the shock tube set-up, a typical oscilloscope output, a mylar disk before and after rupture, and a close-up of the shock tube control panel.
