Can someone help me solve these conceptual questions. Any help is appreciated

3. (a) List two (2) things you would do to reduce the chances of cavitation when designing a pumping system to carry water between two reservoirs. 2 pts (b) What two (2) strategies would you adopt to reduce water hammer effects in a water distribution network. 2 pts (c) You are designing a stilling basin to create a hydraulic jump for energy dissipation. You can create either a strong jump (70-85% energy dissipation) or a steady jump (45-70% energy dissipation). Which of these jumps would you prefer and why? 2pts (d) In hydraulic engineering, pumps in series are preferred when.nd pumps in parallel have the advantage of.pts (e) At a point inside a pipe carrying water (25°C at sea level), the gage pressure is 2.34 kPa. Does cavitation occur at this point? 2 pts (f) In the design of a culvert, list one possible reason that would make you opt for free entrance conditions over submerged entrance condrtions? 2 pts (g) Is the hydraulic radius of a square-shaped culvert 1m x 1m greater than, equal to, or less than that of a circular-shaped culvert of diameter 1 m when they both flow full? 2 pts (h) A globe valve is installed along a pipe which carries water at 1.4 m/s. When the valve is fully open, the value of the minor loss across it is about... 2 pts. (i) TRUE or FALSE: For these three headloss/flow equations in pipes: Manning's, Hazen- Williams', and Darcy-Weisbach's, the respective numerical values of n, CHw, and f all increase as the roughness of the pipe increases. 2 pts. ) Overall this semester, what lecture/part/topic of this course would you say interested you the most? 2 pts 4

Explanation / Answer

3) a)two things to reduce the chances the cavitation-:

i) cavitation can be reduced by installing an impeller inducer.

ii) Increase pump suction line size to reduce turbulence.

b) Water hammer can be reduce by following_

i) from use of surge tank water can be allowed to enter and exit in the condition when water hammer ocurs

ii) water hammer can also be reduced by reducing the velocity and velocity cn be reduced if we use pipe of large diameter.
