What is the resulting steady flow now? How does the vector diagram change? Is it physically sensible (e.g., has friction reduced the speed of the flow)?
At the beach, atmospheric pressure is 1025 mbar. You dive 15 m down in the ocean and you later climb a hill up to 250 m elevation. Assume the density of water is about 1000 kg/m3 and the density of
What is the magnitude of the angular momentum?The current distance is 125.6AU from the sun , assuming Voyager 1 was always on its hyperbolic trajectory, calculate the true anomaly at this position.
A 2.5 m tall steel cylinder has a cross sectional area of 1.5 m2. At the bottom with a height of 0.5 m is liquid water on top of which is a 1 m high layer of gasoline. The gasoline surface is expos
A cannon-ball of 5 kg acts as a piston in a cylinder of 0.15 m diameter. As the gun-powder is burned a pressure of 7 MPa is created in the gas behind the ball. What is the acceleration of the ball i
Calculate the angle between periapsis and the equatorial plane. Calculate the angle between i and the point where the satellite intersects the orbital plane with negative velocity in the k-direction
A valve in a cylinder has a cross sectional area of 11 cm2 with a pressure of 735 kPa inside the cylinder and 99 kPa outside. How large a force is needed to open the valve?
A vertical hydraulic cylinder has a 125-mm diameter piston with hydraulic fluid inside the cylinder and an ambient pressure of 1 bar. Assuming standard gravity, find the piston mass that will creat
A 15-kg steel gas tank holds 300 L of liquid gasoline, having a density of 800 kg/m3. If the system is decelerated with 6 m/s2 what is the needed force?
A tornado rips off a 100 m2 roof with a mass of 1000 kg. What is the minimum vacuum pressure needed to do that if we neglect the anchoring forces?
What is the deflection, w(t) of a Simply supported beam of varying Load P(t) w.r.t time applied at center. Consider Maxwell assumption, so it has non-linear term. Hint:For steady state beam deflect
When you move up from the surface of the earth the gravitation is reduced as g = 9.807 - 3.32 × 10-6 z, with z as the elevation in meters. How many percent is the weight of an airplane reduce
A tank has two rooms separated by a membrane. Room A has 1 kg air and volume 0.5 m3, room B has 0.75 m3 air with density 0.8 kg/m3. The membrane is broken and the air comes to a uniform state. Find
A 5 m3 container is filled with 900 kg of granite (density 2400 kg/m3 ) and the rest of the volume is air with density 1.15 kg/m3. Find the mass of air and the overall (average) specific volume.
The other is moving upward at a constant velocity v2. If we consider the fluid Newtonian, solve for the velocity profile using our newlydefined Navier-Stokes Eqns.
On the moon the gravitational acceleration is approximately one-sixth that on the surface of the earth. A 5-kg mass is "weighed" with a beam balance on the surface on the moon.
A car of mass 1775 kg travels with a velocity of 100 km/h. Find the kinetic energy. How high should it be lifted in the standard gravitational field to have a potential energy that equals the kinet
The pressure at the bottom of a swimming pool is evenly distributed. Suppose we look at a cast iron plate of 7272 kg lying on the ground with an area of 100 m2. What is the average pressure below t
