Unformatted text preview: , is = = p 998 kg / m 3 Q p 1 . 00 10 6 m 2 / sec Q = 9 . 98 10 4 kg / (m sec) To simplify the calculations, it is worthwhile to express the pressure difference in terms of the basic units, viz., 1 Pa = 1 N/m 2 = 1 (kg m/sec 2 )/m 2 = 1 kg/(m sec 2 ). Thus, the pressure difference and the radius are p 1 p 2 = 40 kg / p m sec 2 Q and R = 0 . 025 m Therefore, the maximum velocity is u m = [40 kg / (m sec 2 )] (0 . 025 m) 2 4 [9 . 98 10 4 kg / (m sec)] (120 m) = 0 . 052 m / sec and the Reynolds number is Re = p 998 kg / m 3 Q (0 . 052 m / sec) (0 . 025 m) 9 . 98 10 4 kg / (m sec) = 1300...
