An adiabatic piston-cylinder device equipped with a spring maintains the pressure inside at at 300kPa when the volume is 0, and 3000kPa when the volume is 5 m3. The device is connected to a steam line maintained at 1500kPa and 200 C, and the initial volume is 0. Determine the final temperature (and quality if appropriate) when valve is opened and steam in the line is allowed to enter the cylinder until the pressure inside matches that in the line. Also determine the total work produced during this adiabatic filling process.
A ground level source is emitting pollution. An air sampler is located 1 km downwind and 0.5km crosswind of the source measures the concentration of the pollutant ant ground level as 10 micrograms/cubic meter.
Determine the vertical deflection in inches at the midpoint, called point F, between points B and C. Use E=29,000 Ksi, I=800 inches^4, and A=6.0 inches^2 for all members. Use the Virtual Work Method.
Axis of the hole is perpendicular to VP. Draw elevation, plan and development of the lateral surfaces of the pyramid.
The PVC pipe weighs 36.1 pounds per foot of length. Determine the minimum uniform thickness (in) of concrete (150 lbs/ft^3) required around the exterior of the PVC pipe to prevent the empty pipe from floating.
Past experience indicates that the time for high school seniors to complete a standardized test is normal random variable with a mean of 35 minutes.
A 2.50-g sample of a large biomolecule was dissolved in 13.0 g of carbon tetrachloride. The boiling point of this solution was determined to be 77.85°C. Calculate the molar mass of the biomolecule.
What couple moment does he exert. How much could he exert if he moved his hands to the ends so that his hands are 254 inches apart. What force must he apply at the ends to achieve the same couple moments as when he held his hands 18 inches apart.
The rope is 16 m long and the tree limb is 8 m above the man's center of gravity where he holds the rope. Suppose that the man begins at rest right next to the child and backs away with an acceleration of 0.2 m/s^2.
When using singularity functions, if I have a reactionary moment at a cantilever connection, do I use the right hand rule to solve the moment and determine it's direction through the reactions
The 3.5-Mg engine is suspended from a spreader beam having a negligible mass and is hoisted by a crane which exerts a force of 40 kN on the hoisting cable. Determine the distance the engine is hoisted in 2.4 s, starting from rest.
while groundwater andinfiltration losses over the period were estimated to be 0.6 inches. Determine the combined amounts of water evaporated and transpired from the region during the year of record.
Assuming that the average stack gas velocity is 10.0 m/s and stack is circular with a 3.0 meter diameter, calculate the mass emissions rate of NO2 in kg/day.
