Question

An oscillating plate is below sea water at 20°C. If the velocity of the plate is u=20*cos(4*t) m/s, а.at what height above the plate is the maximum velocity 10 m/s? at what height above the plate is the maximum velocity 15 m/s? C.at what height above the plate is the maximum velocity 19.8 m/s? d. Redo parts (a)-(c) for honey. e.At the height at which maximum velocity is 10 m/s, how far does a parcel of honey travel over i. ½ period of plate oscillation ii. 1 period of plate oscillation f.What is the maximum shear stress on the plate when the fluid is sea water? g. What is the maximum shear stress on the plate when the fluid is sea water h. What is the shear stress on the plate when the fluid is sea water and the plate is at its maximum velocity? i.What is the shear stress on the plate when the fluid is sea water and the plate is at its maximum velocity? What is the shear stress on the plate when the fluid is sea water and the plate is at a time when its velocity is zero?
