Fluid originally flows through a tube at a rate of 100 cm3/s. To illustrate the sensitivity of flow rate to various factors, calculate be new flow rate for following changes with all other factors remaining the same as in original conditions. (a) Pressure difference increases by a factor of 1.50. (b) A new fluid wit 3.00 times greater viscosity is substituted. (c) The tube is replaced by one having 4.00 times the length. (d) Another tube used with a 0.100 times the original. (e) Yet another tube is substituted with a radius 0.100 times the original and half length, and pressure difference is increased by factor of 1.50.

In a two-dimensional flow, a force of 20 lbf acts on a small square plate as shown below. Determine the normal stress xx and the shear stress yx .

At a vertical stress of 200 kPa, the void ratio of a saturated soil sample tested in an oedometer is 1.52 and lies on the normal consolidation line. An increment of vertical stress of 150 kPa compresses the sample to a void ratio of 1.43. a) Determine the compression index of the soil. b) The sample was unloaded to a vertical stress of 200 kPa and void ratio increased to 1.45. Determine the recompression index. c) What is the overconsolidation ratio of the soil at stage (b)? d) If the soil were reloaded to a vertical stress of 500 kPa, what void ratio would be attained

The velocity distribution for laminar flow between parallel plates is given by (see picture)   h is distance separating the plates. Origin is placed midway between them. A flow of water is at 15 C with umax = 0.10 m/s amd h = 0.1mm. Calculate the shear stress on the upper plate and give its direction. Sketch the variation of shear stress across the channel

A thin cylindrical tube 80 mm internal diameter and 5 mm thick,is closed at the ends and is subjected to an internal pressure of 6N / m * m ^ 2.A torque of 2009600 N mm is also applied to the tube. Find the hoop stress, longitudinal stress, maximum and minimum principle stresses and the maximum shear stress.

The total cross-sectional area of the load-bearing calcified portion of the two forearm bones (radius and ulna) is approximately 2.0 cm2. During a car crash, the forearm is slammed against the dashboard. The arm comes to rest from an initial speed of 80 km/h in 4.5 ms. If the aum has an effective mass of 3.0 kg, what is the compressional stress that the arm withstands during the crash? Pa Need Help? Read It

For flow over a plate, the variation of velocity with vertical distance y from the plate is given as u(y) = ay - by2 where a and b are constants. Obtain a relation for the wall shear stress in terms of a, b, and m.

A plate situated at distance of 7 mm from a fixed plate is moving at velocity of 4 m/s. The gap between the plates is filled with oil with density of 800 kg/m³ and kinematic viscosity of 1,25-10-4 m²/s. What is the shear stress on the surfaces? Round off the answer to an integer in Pa, but enter the answer without the unit. Answer:
