1. The velocity of a fluid flow over a horizontal plate as shown in Figure 1 is varying so that at a vertex of 10 cm from the bottom of the plate, the maximum velocity is 150 cm/s. Given that the absolute viscosity of the fluid is 0.9 Ns/m² and the specific gravity (S.G) is 0.913. Find the velocity gradients (units: s¹) and shear stresses (units: N/m²) at y =0 cm, y = cm and y = 10 cm from the plate under the following scenarios: (a) linear velocity distribution $u = Ay + B$ and (b) parabolic velocity distribution $u = ay^2 + by + c$. 12 marks y-10 cm U-1.5 m/s Fig.1 Plate

a. The velocity distribution of flow over a plate is parabolic with vortex 30 cm from the plate, where the velocity is 180 cm/s. If the viscosity of the fluid is 0.9 N s/m^2, find the velocity gradients and shear stresses at distances of 0.15 cm and 30 cm from the plate. b. Derive Hagen-Poiseuille equation and state the assumptions made.

Problem 1: If the velocity profile of a fluid over a plate is parabolic with the vertex 20 cm from the plate, calculate the velocity gradients and shear stresses at a distance of 0, 10, and 20 cm from the plate, assuming the viscosity of the fluid is 5 poise. Problem 2: A block slides down on a smooth inclined surface, as shown in Fig below. Determine the terminal velocity of the block if the 0.1 mm gap between the block and the surface contains SAE 30 oil at 60°F (μ = 0.038 N·s/m²). Assume the velocity distribution in the gap is linear, and the area of the block in contact with the oil is 1 cm².
