Thermodynamics

Oxygen at 300 kPa and 100 degrees C is in a piston, cylinder arrangement with an initial volume of 0.1 cubic meters. It is then compressed in a polytrophic process (P*v^n=constant) with n=1.2 to a final temperature of 200 degrees C. a) Calculate the heat transfer for the process b) Draw a P V diagram for the process Show ALL calculations in detail including intergals......assume an ideal gas.

Set of problems on Dynamics & Kinematics

1. a 10.0-kg crate slides along a horizontal frictionless surface at a constant speed of 4.0 m/s. The crate then slides down a frictionless incline and across a second horizontal surface as shown in the figure. h=3 distance from the top of the incline to the bottom of the incline is 4.0m. a. What is the kinetic energy of the crate as it slides on the upper surface? b. While the crate slides along the upper surface, how much gravitational potential energy does it have compared to what it would have on the lower surface? c. What is the speed of the crate when it arrives at the lower surface? d. What is the kinetic energy of the crate as it slides on the lower surface? 2. A 50.0-... click for more

Magnitude of a Force

A 5.0 kg object moving on a horizontal surface has an initial velocity, vi=(5.0i+10.0j) when a force F acts on the object for 3 seconds after which velocity is vf=(10i+30j) m/s. Determine the work done by the force F on the object. What is the magnitude of the force F?
