Task #1
In the side vertical wall of the tank there is a rectangular hole with dimensions a and b, covered by a flat shield, hinged on the upper side on a horizontal axis, around which it can rotate counterclockwise (Fig. 1). Given: a=0.9m; b=0.9m; H=4.0m; l=1.5m.

Task #2
In a flat vertical wall of a reservoir filled with water, there is a rectangular hole with height a and width b, covered by a semi-cylindrical cover ABC (Fig. 2). The upper edge of this hole is at a depth H below the water level in the tank. Given: H=4m; R=0.6m; b=2.0m.

Task #3
From an open reservoir, in which a constant level is maintained, through a steel pipeline (equivalent roughness Ke = 0.1 mm), consisting of pipes of various diameters d and various lengths l, water flows into the atmosphere, the flow rate of which is Q, temperature t (Fig. 3 ). Given: Q = 3 l/s; d1 = 75mm; d2 = 100mm; d3 =50mm; l1 =2m; l2 =2m; l3 =2m; t=400С.

Task #4
A horizontal pipeline made of steel pipes has a section with a parallel connection of pipes, consisting of two lines l1 and l2 and with a diameter of d1 and d2. At points B, C and D, water flow rates QB, QC and QD are given. Given: l1=200 m; l2=600 m; lAB=500 m; lСD=200 m; d1=100mm; d2=100mm; QB=30l/s; QC=24l/s; QD=6l/s; Hsv=30m.

Task #5
Determine the flow rate of water Q, passing through the drainpipe in a concrete dam, if: the pressure above the center of the pipe H, the diameter of the pipe d, its length l. (Fig. 5) Given: H = 9m; d = 1.5m; l=6m.

Task #6
A trapezoidal channel with a slope steepness m and a wall roughness coefficient n=0.025, having a bottom width b, is laid with a bottom slope i. Given: m=1; b=5m; i=0.002; Q=30m3/s.

Task number 7
A road embankment with a height of Hnas, a subgrade width of B=12 m, and a slope of s
