Fluid Mechanics MCG3340 questions with answers

Nomenclature : Introduction The objective of this experiment is to measure the varying pressure across a converging-diverging channel and comparing the pressure with theoretical pressure from Bernoulli’s equation. Bernoulli’s principle states that as the velocity of the fluid increases, the pressure within the fluid decreases. In this lab, we will calculate the pressure based on the measured height of water in each taps for each flow rate. The flow rate measured by taking the time taken by the weight on the side to start moving. g = Gravity = 9.81m/s2 H = height P0 = Atmospheric Pressure v = Velocity A = Cross-sectional Area ρ = density Q = Volumetric Flow Rate m = mass PD = Dynamic Pressure PStatic Measured = Measured Static Pressure PStatic Theoretical = Theoretical Static Pressure PTotal = Total Pressure V = Volume x = position in horizontal direction Result Tube Dimensions Meniscus Height (m) Velocity (m/s) Width (m) Height (m) Area (m2) Flow 1 Flow 2 Flow 1 Flow 2 A 0.038 0.044 0.0017 0.223 0.224 0.1758 0.0841 B 0.038 0.046 0.0017 0.216 0.219 0.1681 0.0804 C 0.038 0.039 0.0015 0.22 0.224 0.1983 0.0948 D 0.038 0.035 0.0013 0.222 0.226 0.2210 0.1057 E 0.038 0.03 0.0011 0.222 0.228 0.2578 0.1233 F 0.038 0.027 0.0010 0.221 0.227 0.2864 0.1370 G 0.038 0.015 0.0006 0.219 0.233 0.5156 0.2466 H 0.038 0.012 0.0005 0.21 0.233 0.6444 0.3082 I 0.038 0.016 0.0006 0.21 0.233 0.4833 0.2312 J 0.038 0.023 0.0009 0.215 0.229 0.3362 0.1608 K 0.038 0.03 0.0011 0.214 0.228 0.2578 0.1233 L 0.038 0.034 0.0013 0.215
