QNo$1\mathrm{.}234$A pipe $50$ mm in dianmeter is $10$ m long and the velocity of flow of water in the pipe is $2\mathrm{.}5$m$/$s$.$ What would be reduction in head loss if the central $2$ m length was replaced by $75$ mmdiameter, the change of section being sudden? Take f$=0\mathrm{.}04$ for the pipes of both diameters.QuestionsDetermine the rate of flow through the pipes as shown in the fig below: $($a$)$ neglecting minor losses;$($b$)$ Considering minor losses$4=300$La$2$oH$=15$m I$5$m$4$a$300$OmL$702101300$nm d$,=200$nnSh$=0-00520-00482*400$nmDetermine the difference in the elevations betvween the water surfaces in the two tankswhich are connected by a horizontal pipe of diameter $400$ mm and length $500$ m$.$ The rateof flow of water through the pipe is $200$ litres$/$s$.$ Consider all losses and take friction factor$=0\mathrm{.}04.$ Also draw the hydraulic gradient line and Total energy line.A syphon of diameter $200$ mm connects two reservoirs having a difference in elevation as$20$ m$.$ The total length of the syphon is $800$ m and the summit is $5$ m above the water levelin the upper reservoir. If the separation takes place at $2\mathrm{.}8$ m of water absolute find themaximum length of the syphon. Take, f$=0\mathrm{.}016$ and atmospheric pressure $=10\mathrm{.}3$ m of water.Three pipes of diameter $600$mm$,450$ mm and $300$ mm and of length $1000$ m$,750$m and$500$ m respectively are connected in series. Find the diameter of an equivalent pipe oflength$2250$ m$.$Marks$6$
