Compute the elevation of TP1 after correcting for “curvature and refraction” given:

“BM A” elevation = 595.00’ (NAVD 88)

BS (plus sight) rod reading on “BM A” = 7.00’ at a horizontal distance of 1,900'

FS (minus sight) rod reading on “TP1” = 1.00’ at a horizontal distance of 1,950'

Please put the final answer in feet.

For a small scale hydraulic power system, the elevation difference between the reservoir water surface and the pond water surface downstream of the reservoir is 20.35. The velocity of the water exhausting into the pond is 7 m/s, and the discharge through the system is 4 m3/s. The head loss due to friction in the penstock (inlet pipe to turbine, under very high pressure) is negligible. Find the power produced by the turbine in kilowatts. Assume specific weight of water is 9810 N/m3 and g = 9.81 m/s2

A 1200 mm deep by 750 mm wide post-tensioned simply supported beam is shown below. The beam spans 12.0 m and is subject to a superimposed dead load of 50 kN/m and a live load of 35 kN/m. Both the superimposed dead load and live load are applied after transfer (after stressing has taken place). The tendon is located at the mid-height of the beam at each end, and its centreline sits 50 mm from the base at midspan. The concrete strength at transfer is 22 MPa, and at maturity is 40 MPa. Assume Ec = 32800 MPa, γc = 24 kN/m3 and ignore any prestress losses.

a)            If Pi = 2700 kN, assess the adequacy of the beam at transfer. In addition, assuming Pi cannot be changed, briefly describe three methods that could be used to ensure the transfer stresses are within code limits.
