Stream power formula
WebExample - Wind Power. The actual available power from a wind mill with diameter 1 m, efficiency 0.2 (20%) - with wind velocity 10 m/s - can be calculated as. P a = (0.2) (1.2 kg/m 3) π (1 m) 2 (10 m/s) 3 / 8 = 94.2 W. … Web1. Locate a straight section of stream at least 20 feet long. Mark the start and end of the length of stream with flags. 2. Measure the width of the stream and record data in Table 1.1 3. Measure the depth (in tenths of an inch) of the stream at 1 foot intervals. Record data in Table 1.2 4. Observe the bottom of the stream.
