9.44 High-speed passenger trains are streamlined to reduce shear force. The cross section of a passenger car of one such train is shown. For a train 81 m long, estimate the shear force (a) for a speed of 81.1 km/hr and (b) for one of 204 km/hr. What power is required for just the shear force at these speeds? These two power calculations will be answers (c) and (d), respectively. Assume T = 10°C and that the boundary layer is tripped at the front of the train. 10 m Problem 9.44

A monitoring program for water flow in an unsaturated soil layer includes sensors to measure the volumetric water content and suction up to a depth of 3 m. The soil is a sand whose hydraulic properties are shown in the figures below. Using the drying curves, draw a quantitatively accurate set of vertical profiles of volumetric water content, pressure head, and total hydraulic head versus depth (with a datum at the base of the soil layer and an elevation head that is positive upward) expected for the following cases:A) The volumetric water content (moisture content) is 10% throughout the profile B) The pressure head is -150 cm throughout the profile C) The total hydraulic head is 100 cm throughout the profile (static no-flow case) Also, report the hydraulic gradient for each case. For parts (a) and (b), calculate the flow rates through the profile. For part (c), calculate the depth to the water table.

9.16 Two vertical parallel plates are spaced 0.012 ft apart. If the pressure decreases at a rate of 100 psf/ft in the vertical z direction in the fluid between the plates, what is the maximum fluid velocity in the Z direction? The fluid has a viscosity of 10-3 Ibf s/ft² and a specific gravity of 0.80. .

Design the reinforced masonry beam in the wall shown below. The wall is to be constructed of fully grouted hollow concrete masonry units in running bond. It is to carry its own weight plus a superimposed dead load of 2.5 kips/ft and a live load of 0.8 kip/ft. Determine the width of the masonry units (by trials), and the amounts of the longitudinal and shear reinforcement required using the strength design method of TMS 402-22. Show the layout of the reinforcements with diagrams. Use fm = 2,000 psi, Grade 60(60 ksi) steel, and Type S Portland cement mortar. Assume that the centroid of the bottom rebar is 3 inches from the bottom face of the beam. ( you may assume that the unit weight of fully grouted concrete masonry is 125 lbs per cubic foot.)
