9.1. To plot the flow potential versus pressure for a quartz diaphragm in a solution of potassium chloride according to the following data: pressure P (Pa) is equal to a) 5 * 103; b) 10 * 103; c) 15 * 103; d) 20 * 103; d) 25 * 103;
e = 8 * 10–2 V; e is 81; n = 1 * 10-3 Pa * s; Xv = 2.1 * 10–2 Ohm – 1 * m – 1; a = 1,2
