An incompressible, isothermal power law fluid is driven down a pipe of radius R and length L by an applied pressure gradient ∂P/∂z (a known negative value). Assume the flow is axisymmetric
The tank failed catastrophically creating a tidal wave of oil which sent nearly 4,000,000 gallons of diesel fuel into the Monongahela River causing a major environmental problem. "A small, uncemente
A pressurized water tank is used as a source of water for a fire hose. The pressure of the air in the top of the tank is 20 atm (gauge).
he angle through which the wires supporting the block rotate as a result of the impact is measured and determined to be 7 degrees. What is bullet’s velocity.
Mesh refinement techniques need to estimate the local error for the techniques to be able update the mesh. What are some of the common error indicators used in mesh refinement? Explain H-enrichment
Define engineering business functionsoutline the inter-relationships between the different processes and functions of an engineering organisation.
Data used to confirm FEM results. These can be any combination of experimental and theoretical information.
An aluminium alloy strut has the hollow regular hexagonal cross-section with side 50 mm each, and a constant thickness 2.5 mm all round along its length, see figure below.
In the introduction, we stated that design is driven by change and need. Some of these drivers are the requirement for safety, efficiency, energy etc. You need to undertake a design analysis on the
A shark tank in the aquarium has a hemispherical glass viewing “bubble” jutting into the water from the side wall. The radius of the bubble is 1m, starting 2m below the water surface. Wh
Imagine you are the part of a product development team which is developing a novel waste heat recovery system to make cars more efficient. You require choosing or designing a heat exchanger for a wa
The figure shows a “square cavity flow”. In this flow the cavity is filled with a fluid and the lid of the cavity moves with a constant velocity.
Carry out a finite element analysis to determine the stress distributions across the cylinder wall when the internal pressure reaches a value that will cause the material to start yielding according
Explain each graph and data table. In the text, refer to each graph and table using appropriate labels.Explain the number (time) obtained by using the “Goal Seek” function.
Throughout a warmer winter or early spring day, wind at 40 deg.F is blowing at a speed of 40 mph parallel to the 12 foot high by 30 foot long wall of a house. Supposing the interior wall surface is
Design a compensator such that the step response of the system yields the following changes.
Calculate the minimum critical Euler axial compression force, σcr and the minimum critical Euler axial compression stress, σcr, for the column below which is pinned at the top and bottom e
Determine the angular acceleration of the plate at the instant it is released. What is the angular acceleration if the plate was rotating in horizontal plane?
What the essential condition for a heat transfer process to occur.
Compute the direction and magnitude of the maximum principal stress.
The objective of Part I is to propose a feasible design of a microscale device (“microdevice”) that allows tensile tests to be performed on specimens only several hundred nanometers in d
Wind turbines are becoming more and more common as a method of energy production, wind turbines by their very nature are dynamic and are subject to and create their own internal and external kinetic
