5. A somestic water preservation tank in a municipality is 13.5 m below the main reservoir. The water is supplied from the main reservoir through a 3 km pipeline that has a sudden contraction from 200mm in diameter to 150 mm diameter. The contraction is at a point 1.5m below the surface level of the main reservoir. The coefficient of friction for both sections of the pipeline is 0.005. At the contraction point the pressure should not fall below the atmospheric pressure of 3 m of water. Neglecting all the minor losses, calculate the maximum allowable length from the contraction to the domestic tank.

60 degree F water flows through a horizontal turbine. The water speeds at the turbine inlet and the turbine outlet are identical. The water gage pressure at the turbine inlet is 46.4 psi while that at the outlet is 12.2 psi. Assume water frictional losses through the turbine are negligible. Deterimine the shaft work rate in ft*lb per slug of water passing through the turbine. Answer with a positive number if mechanical energy goes into the water and a negative number if mechanical energy comes out of the water as it passes through the turbine.
