1. a. A fluid of density 1400 kg/mand viscosity of 0.9 kg/m.s flows through an 80 mm diameter pipe with a velocity of 5 m/s. What type of flow exists in the pipe? Justify your answer. (2 marks) b. A shaft 70 mm in diameter is being pushed at a speed of 400 mm/s through a bearing sleeve 70.2 mm in diameter and 250 mm long. The clearance, assumed uniform, is filled with oil with kinematic viscosity v = 0.005...
A fluid having a viscosity u 9.35 x 104 lbf-s/ft is contained between two parallel plates, each of which has a cross section of 200 in2. The bottom plate is fixed whereas the top plate moves at a constant velocity of 4 ft/s when a shearing force is applied. The separation distance between the plates is a uniform 0.05 in. Assume the velocity distribution in the fluid is linear. Determine the following: 4. the shear stress in the fluid (lbf/in2)...

Learning Goal: To determine the angle of twist for a circular shaft that is composed of varying cross sections and that is subjected to a given power and frequency load. As shown, a shaft is composed of five cylindrical sections. A motor is attached at Fand supplies the shaft with P = 235.0 hp at a speed of w = 1800 rpm. This power is transferred through the shaft without any loss and is completely removed by the pulley at...
Please Show work Assume that the wall shear stress, Tw, created when a fluid flows through a pipe (see Figure a) depends on the pipe diameter, D, the flowrate, Q, the fluid density, p, and the kinematic viscosity, U. Some model tests run in a laboratory using water in a 0.2-ft-diameter pipe yield the vs. Q data shown in Figure b. Perform a dimensional analysis and use model data to predict the wall shear stress in a 0.5-ft-diameter pipe through...
North Platt Machinery Company manufactures a shaft that must fit inside a sleeve. The firm has just received an order of 44,000 units from Southernstar Exploration Company for $52 per unit. North Platt can manufacture the shaft at $22 per unit. Southernstar desires the diameter of the shaft to be 1.290 cm. The diameter of the shaft must not be less than 1.265 cm in order to fit properly inside the sleeve. To be able to insert the shaft into...
