Please help me with this problem clearly. List two sources of error in the water-filled tube and pressure gauge method of measuring head for a hydro system and how to avoid them. Using this method, a series of measurements up a hill to the source of the stream produces the following heights: 1.5m, 0.7m, 1.0m, 1.9m, 1.6m, 0.3m, and 0.8m. What is the total head for this site? If the flow rate was 0.5 m3s-1, calculate the power available in this stream?
The pressure loss p in a pipe is related to the flow rate Q by the equation P = KQ^n, where K and n are constants. If K = 190 x 10³determine the value for n when a flow rate of Q = 0.04 m³/s causes a pressure loss of 180 Pascals.

3:'A hydraulic oil is flowing in a horizontal drawn steel hydraulic tube ( ɛ = 1.5 x 10-6m) with an ID of 0.047m. A pressure difference of 68 kPa is || observed between two points in the tube 30 meters apart. The oil has a specific gravity of 0.90 and a dynamic viscosity of 3.0 × 10¬³P ·s. Calculate the velocity of the flow of oil using Method Il-C iteration.
A pitot tube is inserted into an air flow to measure the flow speed to measure flow speed. The Pitot tube is inserted into a 100mm diameter tube so that it points upstream into the flow and the pressure as show in figure 5 where p0 = stagnation point. The static pressure is measured at the same location in the flow, using a U-tube differential manometer. Consider density of air equal to 2.3kg/m3 and determine the air flow rate.

Sheet 1 Page 1 of 2 Q1/ An orifice meter is to be calibrated for the measurement of the flow rate of a stream of liquid acetone. The differential manometer fluid has a specific gravity of 1.10. The calibration is accomplished by connecting the orifice meter in series with a rotameter that has previously been calibrated for acetone, adjusting a valve to set the flow rate, and recording the flow rate (determined from the rotameter reading and the rotameter calibration curve) and the differential manometer reading, h. The procedure is repeated for several valve settings to generate an orifice meter calibration curve of flow rate versus h. The following data are taken.
