Question

Shows the pressure-flow characteristics of a small blower at speeds n1 and n2 along with at load characteristics l1 and l2. The blower has a rated air performance of 360 m3/hr at a rated pressure of 15 cm h2o at 250c. For a pressure, p and flow rate, q the load characteristics are expressed as: l1: p = k1q2 l2: p = k2q2 where k1 and k2 are constants. Values of the operating points marked as q1, q2, q3 and q4 are given by: q1 = (82,98); q2 = (68, 68); q3 = (108, 76); q4 = (82, 48) density of h2o at 250c = 1000 kg/m3; acceleration due to gravity = 9.81 m/s2
