  1. Consider water flowing upwards through the 22.5o reducing elbow (22.5o angle to horizontal axis). If diameters of the elbow at entrance point and exit points are 0.02540 m and 0.01905 m respectively, elbow is 0.1 m high, velocities of water are 5 m/s and 9 m/s at entrance point and exit point respectively, and density of water is 1000 kg/m3, moment flux correction factor = 1.02.
    1. Determine gage pressure at inlet
    1. Determine vertical component of force of the system, if weight of the system is 0.2 kg.

A three storey structure having a square footprint of 225 m2 is constructed on a clayey deposit. The structure is planned to be supported by square isolated footings having a width of 2m and spaced at 5m center to center. A typical borehole indicates that the soil consists of 2m fill layer at the top (g=17KN/m3) followed by a very stiff clay layer 2m thick (gsat=18.5KN/m3) underlain by a normally consolidated soft clay layer of 4.5m thickness (gsat=17KN/m3) followed by a rock layer extending down to the bottom of borehole. The foundations are laid on top of the stiff clay layer. Water table is located at the top of the stiff clay layer. Undisturbed samples were taken from the middle of each clay layer and consolidation tests done on undisturbed samples indicated the following:

 Stiff Clay: Cc=0.15; Cs = 0.02; Pc = 120 kPa; e0=0.9

 Soft Normally Consolidated Clay: Cc=0.38; Cs = 0.06; e0=1.0

a) Draw a sketch representing the various problem components.

b) The isolated foundations are subjected to a stress of 140 kPa. Calculate the consolidation settlement. Consider the very stiff clay as one layer and divide soft clay layer into two equal sub-layers. Calculate settlement under one typical foundation.

c) What would be the maximum additional stress applied on a central foundation from two neighboring foundations (situated at the left and right sides of the central foundation). Is it necessary to consider the additional stresses from neighboring foundations in the settlement calculations?

d) A concern is the differential settlement between isolated adjacent footings. It was decided to change the design to have the structure founded on a raft foundation subjected to a stress of 45 kPa. Compute the consolidation settlement and comment on the results.

A one-way solid concrete slab is to be used for a simple span
of 18 ft. In addition to its own weight, the slab carries a superimposed dead
load of 50 psf and a live load of 75 psf. Using the strength method with
f ′c = 4 ksi and fy = 60 ksi, design the slab for minimum overall thickness.

(account for weight of slab)
