A drain of rectangular shape, b= 5.4m, d= 1.2m, S= 1* 10. Resize a new dimension for the drain so that it can carry a larger discharge up to 7m³/sec. Also calculate the percentage of the increase in discharge, use n= 0.035.

Q2/ Three pipes are connected in series. The physical properties of the pipes are in Table below. If (PA_PB) = 150 (KN/m²), (ZA-ZB)= 5m, p=1000 (Kg/m³), and u=1.02x106 (m²/s). Calculate the flow rate through the system. Neglect the minor losses.

Dear Sir , Can you slove this please thanks and regards,

Two pipes are connected in series as shown below. The Hazen-Williams coefficient is80 and the total head loss is 30 feet. Determine the volumetric flow rate in gpm.L1 = 1000 ftD1= 10 inL2 = 2700 ftD2 = 18 in

4. Two reservoir A and B, feed a third reservoir C as shown in figure. Assuming constant water level in the figure and making use of the data given in the table below. Compute the discharge in each pipe. Use conventional solution. EL 205 m EL 130 m 2 EL 192 m Q₁ = 0.3963 m³/s, Q₂ = 0.4550 m³/s, Q3 = 0.8513 m³/s Pipe 1 2 3 n 0.011 0.014 0.017 Diameter Length (mm) in (m) 400 500 800 1800 2000 4000

solve

Compute the discharges for the pipes of the network shown below. Use the Hardy Cross method. Only one iteration cycle is required. The Hazen-Williams coefficient is 130 for all pipes. Begin your computation with the assumed discharges given below and verify that they satisfy the continuity requirement. QAB = 2.4 cfs (from A to B)     QBD = 1.5 cfs (from B to D) QBC = 0.3 cfs (from B to C)    QCD = 0.5 cfs (from C to D) QAC = 1.8 cfs (from A to C)

A 1-m diameter new cast iron pipe is 845 m long and has a head loss of 1.11 m. 1. Find the discharge capacity of water for this pipe by Hazen–William’s formula. Use C = 130 2. Find the discharge capacity of water for this pipe by Manning’s formula. Use n = 0.013 3. Find the discharge capacity of water for this pipe by Darcy Weisbach formula.. Use f = 0.014
