    PERMEABILITY HOMEWORK Problem 1: Assume a vertical cylindrical core filled with water. The length of the core is 1 feet and its radius is 1/12 ft. Water density is 62.428 lb-mass/ft3 and water viscosity is 1 cp. We wish to inject additional water into the bottom of the core and flow water from bottom to top through the core where the top of the core is exposed to the atmosphere‚ i..e.‚ the pressure at the top of the core is 14.7 psi. What is the minimum pressure required at the bottom of the core

    be used by formulators to assist in controlling the flow properties of blended or engineered powders. This paper presents the results of an investigation into the effect of the breadth of the particle size distribution on the flow function‚ bulk density and internal friction of four food grade fillers namely; lactose‚ dextrose‚ maltodextrin and sodium chloride. Physical property measurements‚ including particle size and particle shape‚ are presented along with bulk flow properties which were measured

    of 25 and a variance of 9. Find the probability that a measurement selected at random will be between 19 and 31. Solution: The values 19 and 31 must be transformed into the corresponding z values and then the area between the two z values found. Using the transformation formula from X to z (where µ = 25 and σ √9 = 3)‚ we have z19 = (19 – 25) / 3 = -2 and z31 = (31 - 25) / 3 = +2 From the area between z =±2 is 2(0.4772) = 0.9554 Therefore the probability that a measurement selected at random

    experiment is all about buoyancy and density. Buoyancy describes whether objects float or sink. Usually describes how things float or sink in different gasses. Density deals with the amount of mass an object has. Adding salt to the water adjusted the water. Squeeze the bottle hard enough‚ putting pressure to the packet. This causes the bubbles to get smaller and the entire packet to become more dense. Objective: The objective of this experiment is to find the density and buoyancy which is an upward

    Principle: Cyclone desander is based on the principles of centrifugal sedimentation and density difference‚ when the water under a certain pressure from desanding into the equipment by the inlet to tangential‚ it will come about a strong rotation‚ due to the different density of sand and water‚ under the common action of the centrifugal force‚ centripetal force‚ buoyancy and fluid drag force‚ make the low density water rising‚ and expel from the outlet‚ the dense sand will be discharge outlet from

    A group of investors wants to develop a chain of fast-food restaurants. In determining potential costs for each facility‚ they must consider‚ among other expenses‚ the average monthly electric bill. They decide to sample some fast-food restaurants currently operating to estimate the monthly cost of electricity. They want to be 90% confident of their results and want the error of the interval estimate to be no more than $100. They estimate that such bills range from $600 to $2‚500. How large a sample
