1.From a point 1, a 25mm diameter pipe runs horizontally under the floor and then a 12.5 mm diameter line runs 1 m up the wall to a point 2. To maintain a pressure of 300kPa at point 2, what the 15 C water is flowing at 0.5 L/s, what pressure must be provided at point 1 if you neglect friction?
2.A pressure gage at elevation 4.8 m on the side of a storage tank containing oil reads 34.7 kPa.Another gage at elevation 2.2 m reads 57.5 kPa. Compute the specific weight, density, and specific gravity of the oil.
