Answer: ![10.631\times 10^3\ N/m^2](https://tex.z-dn.net/?f=10.631%5Ctimes%2010%5E3%5C%20N%2Fm%5E2)
Explanation:
Given
Discharge is ![Q=12.5\ L](https://tex.z-dn.net/?f=Q%3D12.5%5C%20L)
Diameter of pipe ![d=150\ mm](https://tex.z-dn.net/?f=d%3D150%5C%20mm)
Distance between two ends of pipe ![L=800\ m](https://tex.z-dn.net/?f=L%3D800%5C%20m)
friction factor ![f=0.008](https://tex.z-dn.net/?f=f%3D0.008)
Average velocity is given by
![\Rightarrow v_{avg}=\dfrac{12.5\times 10^{-3}}{\frac{\pi }{4}(0.15)^2}\\\\\Rightarrow v_{avg}=\dfrac{15.9134\times 10^{-3}}{2.25\times 10^{-2}}\\\\\Rightarrow v_{avg}=7.07\times 10^{-1}\\\Rightarrow v_{avg}=0.707\ m/s](https://tex.z-dn.net/?f=%5CRightarrow%20v_%7Bavg%7D%3D%5Cdfrac%7B12.5%5Ctimes%2010%5E%7B-3%7D%7D%7B%5Cfrac%7B%5Cpi%20%7D%7B4%7D%280.15%29%5E2%7D%5C%5C%5C%5C%5CRightarrow%20v_%7Bavg%7D%3D%5Cdfrac%7B15.9134%5Ctimes%2010%5E%7B-3%7D%7D%7B2.25%5Ctimes%2010%5E%7B-2%7D%7D%5C%5C%5C%5C%5CRightarrow%20v_%7Bavg%7D%3D7.07%5Ctimes%2010%5E%7B-1%7D%5C%5C%5CRightarrow%20v_%7Bavg%7D%3D0.707%5C%20m%2Fs)
Pressure difference is given by
![\Rightarrow \Delta P=f\ \dfrac{L}{d}\dfrac{\rho v_{avg}^2}{2}\\\\\Rightarrow \Delta P=0.008\times \dfrac{800}{0.15}\times \dfrac{997\times (0.707)^2}{2}\\\\\Rightarrow \Delta P=10,631.45\ N/m^2\\\Rightarrow \Delta P=10.631\ kPa](https://tex.z-dn.net/?f=%5CRightarrow%20%5CDelta%20P%3Df%5C%20%5Cdfrac%7BL%7D%7Bd%7D%5Cdfrac%7B%5Crho%20v_%7Bavg%7D%5E2%7D%7B2%7D%5C%5C%5C%5C%5CRightarrow%20%5CDelta%20P%3D0.008%5Ctimes%20%5Cdfrac%7B800%7D%7B0.15%7D%5Ctimes%20%5Cdfrac%7B997%5Ctimes%20%280.707%29%5E2%7D%7B2%7D%5C%5C%5C%5C%5CRightarrow%20%5CDelta%20P%3D10%2C631.45%5C%20N%2Fm%5E2%5C%5C%5CRightarrow%20%20%5CDelta%20P%3D10.631%5C%20kPa)
Answer:
Option A
Chemical engineering
Explanation:
Chemical engineering mainly encompass the study of behavior of different particles such as petroleum, water, drugs and other products. When Anne is involved in a study with engineers who study flow of particles, the flow, viscosity and other properties are among the behavior that chemical engineers are involved in.
H is the answer
