Swamee-Jain's assertion that the results are within 1% of each other? 2.7. A straight pipe has a diameter of 25 mm, a roughness height of 0.1 mm, and is inclined upward at an angle of 10°. The water temperature is 20°C. (a) If the pressure at a given section of the pipe is to be maintained at 550 kPa, determine the pressure at a section 100 m downstream for flows of 2 L/min, and 20 L/min (two answers are required here). (b) For a flow of 20 L/min, compare the value of the friction factor calculated using the Cole- brook equation with the friction factor calculated using the Swamee-Jain equation; does your result support
