i really appreciate it if explain this throughly June 1. Consider steady, fully-developed laminar flow of air through a Laminar Flow Element (LFE, a type of flow-meter) with an aligned bundle of 100 small bore tubes, each of diameter D 2.00 mm, and length L 200.0 mm. The pressure drop per unit length (Ap/L) across each of the 100 tubes is a function of the tube diameter D, fuid viscosity u (in units N s/m2), and average air velocity Vave....
LECTURE Sp 1. Oil (relative density 0.85, dynamic viscosity-4.5x10-2kg/m-s) flows through a 75 mm diameter pipe with a mean velocity of 0.65 m/s. Determine i. the pressure drop in a 500 m length, ii- the friction factor, ii the head loss due to friction, iv. the maximunn velocity, and v. the velocity at 30 mm from the pipe wall.

A fluid with an average speed of 2.1 m/s flows through commercial steel tubing with a diameter of 2 mm and a length of 200 m. The tubing contains 10 regular threaded elbows and the discharge end of the tube is 60 m lower than the inlet. Calculate the pressure drop inlet to exit assuming the fluid is: a) air with average properties of 100 C, 200 kPa. b) water at a temperature of 20 C

(5 pts) Continuous tubing is produced in a plastic extrusion operation through a die orifice whose outside diameter = 2.0 in and inside diameter = 1.5 in. The extruder barrel diameter 5.0 in and length = 12 ft. The screw rotates at 50 rev/min; it has a channel depth 0.30 in and flight angle 16°.

1. An oil of density p800 kg/m3 and viscosity u 5 cP flows at 10 liters/min through a 30 m smooth circular pipe of inner diameter 2 cm. It then flows through a filtering section made up of the same pipe packed at void fraction ε-0.4 with solid spherical particles of diameter 0.5 mm to filter out any fine material. All pipe sections are straight as shown. Design constraint: the pressure drop in the packed bed section (call this AP2)...
