Using Raoult's Law or Henry's Law, as appropriate, calculate the pressure and mole fractions in the vapor phase for a system containing a liquid that is 0.3% N2 and 99.7% water (by moles) in equilibrium with its vapor at 80 °C.
Discuss the dangers of optimization in terms of minimum section to support loads. In other words, how would optimizing for bending stresses affect the shear capacity of a section
Given s=.30/(60-u), where s is the spacing (space headway) in miles, and u is the speed in miles per hour, derive the relationships u-k, u-q, and q-k. Also, estmate the capacity (qmax) of the roadway.
The flow rate of water flowing in a 3m wide channel is to be measured with a sharp-crested triangular weir 0.5m above the channel bottom with a notch angle of 60°. If the flow depth upstream from the weir is 1.5m
Select the sentence that is punctuated correctly.
If r = (theta)2 and theta = 2t, find the magnitude of r dot and theta double dot when t = 2 s
Two ships A and B are moving with constant speeds Va and Vb along straight intersecting courses. The navigator of ship B notes the time rates fo change of the separation distance r between the ships and the bearing angle theta.
the structure has a curved face being part of a circle with radius R = 32M. The dam holds water to a height = 28 m. Claculate the magnitude and direction of the resultant force per metre length of the dam wall
Compute the size of a squeare concrete box culvert to handle a discharge of 25.5 cms. The culvert will have a length of 45.7m with a slope of 0.01 and a maximum headwater depth of 4.57m.
The rigid bar of negligible weight is supported as shown. Find the stress in each rod if the temperature rises DeltaT after a load P is applied. Use the following data: area of steal rod 320mm2, bronze rod 1300mm2, thermal expansion coefficient Al..
Write a balanced net equation for the reaction of the hydrogen ascorbate anion with water where hydrogen ascorbate acts as an acid.
Draw the shearing force diagram and the moment diagram of the following problem. The beam is indeterminate. You need to integrate the moment twice to get a formula for the deflection v(x).
Calculate the metric tons of gravel required to fill an excavated area 70 meters by 50 meters by 2 meters deep if the gravel has a density of 1890 kg/(m^3).
