In the pump installation of the figure the characteristic curves (H, Q) and (n, Q) of the pump, for a rotational speed of 2000rpm, are given by the relations H = 84-2.5 * 10 ^ -3 * Q ^ 2 and n = 0, 2 + 0,014Q-10 ^ -4 * Q ^ 2 (H in m, Q in m ^ 3 / h). What is the operating point of the pump for this speed? The coefficient r of the pipe is 0.002 h ^ 2 / m ^ 5 for h in m water and Q in m ^ 3 / h
