Q1. Answer the following questions on condition of fluid. 1-1) In order to obtain the flow rate of the air flowing at constant speed inside the circular tube, NH3 is introduced as 0.50103m3s1 as a tracer. NH3 is detected as a concentration of 0.2 vol % at a completely mixed downstream point. Find the volumetric flow rate V(m3s1) of air. 1-2) Sending some fluid to reservoir B 600m away from reservoir A. The specific gravity of the fluid is 0.74 , and the viscosity is 0.065Pas. When a fluid is flowed at a rate of 100m3 h1 into a steel circular tube with an inner diameter of 200mm, how much does the friction energy loss occur? 1-3) With carbon tetrachloride (1.60gcm3) filled U-tube manometers, the height difference between two points at a circular tube placed horizontally revealed to be 62.5mm. Find the differential pressure between the two points
