A fluid with a specific weight of 100lb/ft^3 and a negligibleviscous effects flows in a pipe. The pipe is inclined at 30degrees. Point (1) is located above point (2) in the pipe. This means that the hypotenuse is 10ft long connecting point(2) to point (1). The Pressure at point (1) is 400 lb/ft^2and 900 lb/ft^2 at point (2). The velocities are equal. Is the fluid accelerating uphill, down hill, or not at all?
The velocity of the center point of the wheel is constant at 20 ft/sec to the right. For the instant, determine the following: a) The velocity and acceleration of point B (which is attached to the wheel) measured with respect to ground.
The compound beam is fixed at A and supported by a rocker at B and C. There are hinges (pins) at D and E. Determine the reactions at the supports.
The water depth before the jump is 0.4 m and after the jump is 1.7 m. Compute the flow rate in the channel, the critical depth and the headloss in the jump.
