Choose one (1) Native American tribe residing within the continental United States (Lower 48 states) at the time of first European contact. Research various aspect of the chosen tribe's culture or history.Topics that need to be researched include but are not limited to:Describing what is known of the tribe's pre-Columbian history, including settlement dates and any known cultural details. Describing the cultural and religious beliefs of the chosen tribe.Describing the tribe's history after contact, including major events and armed conflicts that may have been important to the history of the tribe in the present day.Explaining the history of at least one historical figure of the chosen tribe and events surrounding that individual's life.
It is known that the velocity distribution for steady, laminar flowin circular tubes (either horizontal od vertical) isparabolic. Consider a 10 -mm- diameter horizontal tubethrough with ethyl alcohol is flowing with a steady mean velocity.15 m/s.
(a) Use differentiation to find a general expression for the rocket's velocity as a function of time, (b) When is the velocity zero?
Starting from x = 0 with no initial velocity, the acceleration of a race car is defined by the relation a = 6.8e-0.00057x, where a and x are expressed in m/s2 and meters, respectively. Determine the position of the race car when v = 30 m/s.
Two strips of a plastics material are bonded together as shown. The average shearing stress in the glue must be limited to 1000 kpa.
The traffic that makes a left turnat an intersection consists of two types of vehicles, Type A andB. A type A vehicle is twice the length of the type B. THe left turn lane can accommodate ten vehicles of type B, five oftype A.
Describe how test flumes and associated equipment are used to assess and confirm hydraulic behaviour in open channel
A water supply system is being designed to serve a population of 200,000 people with an average per-capita demand of 600L/Person-day (peak demand factor is 1.8) and a needed fire flow of 28,000 L/min.
Water flows past a triangular flat plate oriented parallel to the free stream. Integrate the wall shear stress over the plate to determine the friction drag on one side of the plate. Assume laminar boundary layer flow.
How would you define the coefficient of permeability? Give typical values of the coefficient for: a) fresh cement pastes; b) hardened cement pastes; c) commonly used aggregates;
The 12 in diameter cast iron pipe is 2000ft long, the water surface is El 200 in the reservoir on the left B. El 175 on the right. A. Find V and Q by hazen-williams for a new cast iron pipe (Chw=130) Neglect entrance, exit and local losses.
The drawdown in another observation well 60 m from the pumping well is 1.1 m. Calculate (a) the hydraulic conductivity of the aquifer, (b) the expected drawdown in the pumping well,
A 1:40 scale model of a ship is tested in a towing tank. Prototype operates in seawater at 60 F. Find a liquid to be used in the towing tank that allows both Froude and Reynolds scaling for the model and the prototype.
