Q2: water flows through a sluice gate in an open channel of a
rectangular cross section with width (𝑏). The water depths upstream
and downstream of the gate are (𝑦1) and (𝑦2) respectively. Given
the values of 𝑦1 [m], 𝑦2 [m], and 𝑏 [m], calculate the discharge in
the channel (𝑄) in [Lit/s]

L2,dz Lj,d1 Problem (13): A pump is being used to lift water from the bottom tank to the top tank in a cast iron pipe at a discharge (Q). The lengh and diameter of the pipe section from the bottom tank to the pump are (L2) and (d), respectively. The length and diameter of the pipe section from the pump to the top tank are (L2) and (dz), respectively. Given the values of Q [L/s], L, [m], d, [m], L2 [m], d2 [m], calculate total head loss due to friction (i.e., major loss) in the pipe (hmajor loss) in [cm]. Pump
