A 4m-long quarter-circular gate of radius 3 m and of negligible weight is hinged about its upper edge A. The gage controls the flow of water over the ledge at B, where the gate is pressed by a spring. Determine the minimum spring force required to keep the gate closed when the water level rises to A at the upper edge of the gate.

4.2m SCHAIN A CHINGE) GATE c.g. 2600 1m The 1 meter diameter gate shown weighs 450N and is hinged at "A" and can be opened by force "T" thru the chain weighing 60N. The center of gravity of the valve 4.2m below the water surface and the dam is inclined by 600 from the horizontal. Determine the force "T" required to open the gate. (Notes: Hydrostatic force "F" is always perpendicular to the plane surface) (A) 30.56 KN B No answer among the choices 33.49 KN D) 39.67 KN (E) 36.24 KN

ASAP dont round in initial values, only round off in final ans plzs

Water flows through the 2-in-diameter pipe at 0.2 ??^3/s as shown in Fig. 5-19a. If the pressure at A is 30 psi, determine the pressure at C, and draw the energy and hydraulic grade lines from A to B. Neglect friction losses and take ?? = 62.4 ??/ft^3
