7. (25 pts) Glycerin flows at 0.005 m''s through the narrow region between the two smooth plates that are 15 mm apart. Assume the plates are wide enough (0.4 m) to neglect end effects. Also, assume a steady, incompressible, and laminar flow. The density and viscosity of glycerin are ρ = 1260 kg/m and u 1.50 N s/m2. Simplified governing equations are sufficient. a) Derive the velocity distribution profile that gives 1 (ap -15mm b) Determine the pressure gradient acting...

2. A steady state solid feed consisting of 4 mm (radius) spherical particles enters a rotating kiln-type reactor (assume plug flow) and reacts with gas of uniform composition at a particular T and P. Experimentally it was determined that the time required for complete conversion of the solid particle was 4 h. a) Calculate the time required for 70% conversion of the solid feed to solid product for 2 mm (radius) particles at the same conditions. Assume the SCM is...
65. The pressure drop along a length of artery is 100 Pa, the radius is 10 mm, and the flow is laminar. The average speed of the blood is 15 mm/s. (a) What is the net force on the blood in this section of artery? (b) What is the power expended maintaining the flow? 66. A small artery has a length of and a radius of .

Problem 3. In a constant-head permeability test, the length of the specimen is 150 mm and the cross-sectional area is 3167 mm". If k = 0.062 cm/sec and a rate of flow of 160 cm/min has to be maintained during the test, what should be the head differ- ence across the specimen? Also, determine the discharge velocity under the test conditions.
Time of concentration Determine the time of concentration (te) for an overland flow length of 200 ft on an area in Colorado Springs, CO, with a Manning's roughness coefficient of 0.10, for a design frequency of 25 years. The rainfall intensity-duration relationship for a 25-year frequency is as given in Table 1. Take the average slope of the area as 0.005 ft/ft. Recall that the time of concentration for inlets is given by: where time of concentration (in seconds) 1-overland...
