speed, the platoon is growing at a rate of:
A tank transmits 100 L/s of water to point C, where the pressure is maintained at 1.5 kg/cm².
The first part, AB of the pipe, is 50 cm in diameter and 2.5 km long, and the second part BC is
25 cm in diameter and 1.5 km long. The friction coefficient is 0.005, and minor losses are
ignored. Assuming the level at C is (0.0), find the water level (L) in the tank.

- The figures below shows the framing plan and section of a reinforced concrete floor system. Floor beams are shown as dotted lines. The weight of the ceiling and floor finishing is 6 psf, that of the mechanical and electrical systems is 7 psf, and the weight of the partitions is 180 psf. The floor live load is 105 psf. The 7 in. thick slab exterior bay (S-1) is reinforced with #5 rebars @ 10 in. o.c. as the main positive reinforcement at the mid span, and #4 @ 109 in. for the shrinkage and temperature reinforcement. The panel is simply supported on the exterior edge and monolithic with the beam at the interior edge. Check the adequacy of the slab. Use the ACI moment coefficients. fc’ = 6,000 psi and fy = 60,000 psi. The slab is in an interior location. Hint: • Estimate total dead load.
