Extracted text: e. A 0.5m x 2m flat plate is towed at 5 m/s on a 2-mm-thick layer of SAE-30 oil at 38°C that separates it from a flat surface. The velocity distribution between the plate and the surface is assumed to be linear. What force is required if the plate and surface are horizontal? Final Answer: 250 N (Use: viscosity = 0.1 N-s/m2) f. A machine creates small 0.5-mm-diameter bubbles of 20-C water. Estimate the pressure that exists inside the bubbles. At 20° C, surface tension of water is 0.0736 N/m. Final Answer: 589 Pa
