Document Content and Description Below

6/23/20 Lab 8 Fluid Pressure: 1. If the top of the reservoir (the ground/grass) is at Atmospheric Pressure (1 ATM = 101.325 kPa), predict from the appropriate equation above what the pressure will... be at the bottom. Show your work in your lab report. P❑ atm=101.325kPa=1.01325 x105 Pa P❑ bottom=P❑atm+ p❑w gh P❑bottom=1.01325x 105 Pa+(1000kg/m3)(9.8N)(3m) P❑ bottom=130,725 Pa P❑ bottom=130.725kPa 2. Measure the pressure at the bottom by using the Pressure gauge. Do your predicted and measured results agree? Using the Pressure gauge feature of the simulation, we found the pressure at the bottom of the reservoir to be 130.7 kPa. Our predicted and measured results agree. 3. Note that you can change the composition of the fluid in the reservoir; the default was Water. Now change it to Honey and repeat steps 1 and 2 above; do your new predicted and measured results still agree? Using honey, the density changes to 1420kg/m3 P❑ bottom=P❑atm+ p❑w gh P❑bottom=1.01325x 1 05 Pa+(1420kg/m3)(9.8N)(3m) P❑ bottom=143,073Pa P❑ bottom=143.073 kPa Using the Pressure gauge feature of the simulation, we found the pressure at the bottom of the reservoir to be 143.0 kPa. Our predicted and measured results agree. Fluid Flow: [Show More]
