A satellite rotates around the globe at 16,000 km/h. To reenter into the atmosphere, the speed is reduced by 1000 km/h by firing a small rocket in the direction opposite that of the satellite's motion.
(a) What are the velocity vectors of the satellite before and immediately after firing the rocket.
(b) Find the scaling factor of the original velocity vector required to get the satellite to its new speed.
Water in a vertical piston cylinder is heated at constant pressure of 10 bar. It is initially at 179.9 0C and has a specific volume of 0.1 m3/kg and is heated to a final specific volume of 0.248 m3/kg. Changes in kinetic and potential energies are ze..
a stone is released from an elevator moving up at a speed of 12 fts and reaches the bottom of the shaft in 2.5 s. a how
a large plate contains a central crack of length 2 mm and is subjected to a cyclic stress normal to the crack which
A high-speed boat is powered by a water jet pump engine, similar to a jet engine on airplanes. The engine takes in water at the bow through a tube with diameter 1 ft, and the water is pumped out the stern of the boat through a 3-in diameter tube. The..
hot water at 60 c enters a thin copper tube with an inside dia of 6mm and a length of 20m. the copper tube is exposed
a fully automated production line in a facility involves metal blocks being placed in a furnace for heat treatment. two
A gasoline engine is modeled as an Otto cycle. It has at temperature and pressure at the beginning of compression of 10°C and 90 kPa. The compression ratio is 7 and the specific energy added to the air during the heat addition process is 1432.46 ..
Calculate the average distance between dislocations for both cases. For sim- plicity, assume all of the dislocations are parallel and in a square pattern.
Solve for the pressure of a gas using both equations at a temperature of 400K and a molar volume of 1x 10-4 m3/mol. For the van der Waals EOS, use parameters of a= 4.1x10-1 (m3/mol)2 Pa, and b=4.3x10-5 m3/mol.
