A well-insulated rigid vessel of volume 0.2 m^3 is divided into two equal compartments by thin diaphragm, as illustrated in the accompanying figure. One of the compartments is a vacuum. The other is a fluid at a pressure of 200 kPa and a temperature of 125 degrees Celsius. The diaphragm is ruptured and fluid fills the entire volume of the vessel. Assume that the fluid is an ideal gas. After you have determined Qsub12, Wsub12, and delta U for the process, calculate the final temperature of the gas.
A sample of 20 yields a mean 32.4. Test the two sided hypothesis that the sample drawn from a population with a mean of 35 for the following cases. (a) if a variance of the population is 33; and (b) if the variance of the population is unknown,
you are designing a highway to AASHTO guidelines on rolling terrain where the design speed will be 65 mi/hr. At one section, a +1.25% grade and a -2.25% grade must be connected with and equal tangent vertical curve.
Determine the velocity of slider block C at t=0, (b) the acceleration of A and C, (c) the change in position of block A after 5s.
Calculate the stress at failure of a concrete test cylinder with a measured diameter of 152.4 mm and a recorded load of 371,426N. Units of ksi.
Determine the diameter of glass tubing that is necessary for the capillary rise to be less than 0.5 mm. Assume the fluid is water with surface tension equal to 0.0728 N/m and specific weight equal to 9800 N/m3
Rainwater runoff from a 200 x 500 ft parking lot is to drain through a circular concrete pipe that is laid on a slope of 5 ft/mi. Determine the pipe diameter if it is to be full with a steady rainfall of 1.5 in/hr
what is the uniform deterministic arrival rate if the vehicle queue is cleared in 35 minutes after vehicles begin to arrive (in veh/min.)?
indicate the conditons by a sketchand determine the difference in the rate of grade at the intersection of each of the following paris of slops.
Determine the design hourly volume for the road below, recommend the K factor first.
Vehicles begin to arrive at a toll booth at 850 am with an arrival rate of x(t) = 4.1 + .01t (with t in min and x(t) in veh /min.) The toll booth opens at 9am and processes vehicles at a rate of 12 per minute throughout the day. Assuming D/D/1 que..
two solid rods AB and BC are welded together at B and loaded as shown. Knowing that d1=50mm and d2=30mm, find average normal stress at the midsection of rod AB and rod BC.
Constructing the foundation causes changes in the levels of vertical stress at all points in the soil. One such point lies at the centre of the footing plan, and is at a depth of 10 m. Determine the increment of vertical stress there.
