3.5 m चौड़ी और 2.5 m पानी की गहराई वाली एक आयताकार खुली नहर से प्रवाह (Discharge) की गणना करें, जिसका पेंदा ढाल 2000 में 1 है। (बाज़िन सूत्र में K = 2.36 लें।)

In a two-dimensional flow around a cylinder, the discharge between two streamlines which are 0.2 m apart is 0.05 m3/s per one-metre depth of flow. Determine the average flow velocity (in m/s) between these streamlines.

An open cubical tank of side 2 m is filled with water. If the tank is accelerated horizontally such that half of the water spills out, then the acceleration of the tank is equal to:
