Chapter 15, Problem 1P
To determine

The change of local friction coefficient with position.

Expert Solution & Answer
Check Mark

Explanation of Solution

The local friction coefficient accounted to calculate the drag force at specific location. The variation in the velocity of the boundary layer in the flow direction causes the local friction coefficient to vary along the surface of the flat plate. The local friction coefficient is denoted as Cf,x.

The variation of local friction coefficient with the position for the laminar flow along the flat plate is shown in below figure.

The local friction coefficient Cf,x decreases with downstream as the distance x increases in a laminar flow over a flat plate.

Water is supplied at 150 ft³/s and 70 psi to a hydraulic turbine through a 3-ft inside-diameter inlet pipe as indicated in the figure below. The turbine discharge pipe has a 4.8-ft inside diameter. The static pressure at section (2), 10 ft below the turbine inlet, is 10 in. Hg vacuum. If the turbine develops 2400 hp, determine the rate of loss of available energy between sections (1) and (2).

This problem studies the response of two single degree of freedom bridge systems shown in Figure 1 under three loading cases. The problem has two parts. Part A and Part B use the same loading cases but the system is modified. Assume the following three loading cases in both Part A and Part B: (a) Harmonic wind load acting on the bridge deck pw(t) = powsin(ωwt) with amplitude pow and forcing circular frequency ωw. (b) Harmonic displacement base excitation acting at the base of the bridge pier ug(t) = ugosin(ωgt) with amplitude ugo and displacement circular frequency ωg. (c) Rectangular pulse load acting on the bridge deck with amplitude pop and pulse duration td. Part A  The system includes part of a bridge deck and a bridge pier shown in Figure 1(a). For each loading case find the symbolic expression of the peak shear force in the bridge pier assuming the following: • The bridge deck is rigid and it has a mass m. • The bridge deck is rigidly connected with the bridge pier (i.e.,…
