A rigid tank whose volume is 10L is initially evacuated. A pinhole develops in the wall, and air from the surroundings at 1 bar, 25 degrees Celsius enters until the pressure in the tank becomes 1 bar. NO significant heat transfer between the contents of the tank and the surroundings occurs. Assuming the ideal gas model with k=1.4 for the air, determine
(a) the final temperature in the tank, in degrees Celsius, and (b) the amount of air that leaks into the tank, in g.
If the time required to pay for parking is exponentially distributed with a mean of 15 seconds, find the average time in system.
create a primary function that uses a function handle with a nested function to compute the ninimum of the function 20x^2-200x+12 over the range 0
What power must the pump supply to the system to pump the oil from the lower reservoir to the upper reservoir at a rate of .2 m^3/s. Sketch the HGL and the EGL for the system.
An 8-inch water main with a flow rate of 14 ft3/sec raises 100-feet. At the beginning of the main the pressure is 110 psig and drops to 50-psig at the end. For this water main calculate the head loss
Parallel pipes, fixed overall H, ?EGL or hl = 75'. Elevated Tank A water surface is at El 625, 3000' away is Tank B with free surface El 550 They are connected by a 12" dia cast iron pipe.
The tank is heated to a pressure of 10 bar. Assuming that Xe behaves like an ideal gas with a specific heat ration of 1.7, Calculate the amount of heat transferred during the process in Kj.
Let E be an unsorted set of n segments that are the edges of a convex polygon. Describe an O(nlogn) algorithm that computes from E a list containing all vertices of the polygon, sorted in clockwise order.
Course AB of a five-sided traverse runs due east. From the given balanced interior angles (listed below) to theright, compute and tabulate the bearings and azimuths from northfor each side of the traverse.
Oil (SAE 30) flows between parallel plates spaced 5mm apart. The bottom plate is fixed, but the upper plate moves with avelocity of .2 m/s in the positive x direction. The pressuregradient is 60 kPa/m, and is negative.
In magnetic tape recording, the tape is subjected to tension while it is guided along its path. Tension in the tape causes elastic deformation that results in slight changes in length of the domains on which information is stored.
The acceleration of a particle is defined by the relationship a=-kx^-2 ft/s^2, where x is in feet and k is a constant. At x(0)=0.1ft, v(0)=0 and at x(1)=1ft, v(1)=10ft/s. Find the velocity at x=5ft.
a gate shaped like .25 of a cylinder with radius r3m is used to control the flow of water through a canal.the height of
