1) why we multipled with 1/10?

2)why the are is only 1.5 ? why its not 1.5 * 10^-3 * 10^6

Your Tum: A flat plate of area 1.5106mm2 is pulled with a speed of 0.4m/s relative to another plate located at a distance of 0.15mm from it. Find the shear force and power required t? maintain this speed, if the fluid separating them has a viscosity of 0.1 Pa.s Image transcription Show full question Expert answer This solution is designed to help students like you learn core concepts. A azxasf Solution: Given: Area of the plate, A=1.5106mm2=1.5m2 Speed of plate relative to another plate, Distance between the plates, du=0.4m/s Viscosity dy=0.15mm=0.15103m =1 poise 101m2Ns. Using equation (1.2), we have =dydu=1010151030.4=266.66m2N (i) Shear force, F=area=266.661.5=400N
