A converging-diverging nozzle is attached to a compressed air reservoir at 1.00 MPa and 27.0°C.
There are two positions in the nozzle where A/A* = 2.00, one is in the converging section and the other is in the diverging section.
Determine the Mach number, pressure, temperature, density, and velocity at each section.
A truck with 0.420 m radius tires travels at 34 m/s. What is the angular velocity of the rotating tires in radians per second
consider a hot-air balloon. the deflated balloon gondola and 2 passengers have a combined mass of 315 kg. when inflated
A 100 kilogram crate is pushed at a constant speed up a frictionless, 30o inclined ramp. Find what constant horizontal force is required
A bullet weighing 5 g is fired horizontally into a 2 kg wooden block resting on a horizontal table. The bullet is arrested within the block which moves 2 m. If the coefficient of kinetic friction between the block and surface of the table is 0.2, ..
To construct a solenoid, you wrap insulated wire uniformly around a plastic tube 14cm in diameter and 55cm in length, What is the total length of wire you will need to meet these specifications
a 1025 kg van stopped at a traffic light is hit directly in the rear by a 737 kg car traveling with a velocity of 2.30
There are two major types of aberration (defective image formation) in lenses: spherical and chromatic. Spherical aberration comes from fact that a spherical lens has the property of focusing parallel rays to a single point only approximately.
Using Newtons version of Kepler's third law, find their two orbital periods. Find the percent difference in their distances from Saturn and in their orbital periods.
A wire 25.1 m long and 6.00 mm in diameter has a resistance of 15.0 m. A potential difference of 27.0 V is applied between the ends. Calculate the resistivity of the wire material
You are in a hot air balloon (yes, another balloon problem!) rising from the ground at a constant velocity of 2.70 m/s upward. To celebrate the takeoff, you open a bottle of champagne, expelling the cork with a horizontal velocity of 4.00 m/s rela..
When n moles of an ideal gas is allowed to expand from an initial volume of 10 m3 at a constant temperature T the work done is equal to : - nRT ln 4, What was the final volume of the gas
n = 4.13 mol of Hydrogen gas is initially at T = 335 K temperature and pi = 1.73×105 Pa pressure. How much entropy did the gas emit
