Select an appropriate pipe diameter and size of pump using Fig. 10.3 to deliver water at Q ¼ 250 m3=h between two reservoirs. The maximum allowable pipe velocity is 3 m=s, the length of the line is 1500 m, and the difference in elevation between the reservoirs is 30 m. Assume f ¼ 0.02 and K ¼ 0.5.
Consider a simple pendulum of length l and mass m placed in a rail-road cart that has constant acceleration a in the positive x-direction. Obtain Hamilton's canonical equations of motion for this pendulum.
q1. a 25- sample of an ideal gas with is at 250 and 50. the gas is compressed isothermally to one-third of its original
A polytropic process for an ideal gas in one in which pressure and volume are related by = const., where n is a constant. It is a generalization of the special processes considered earlier. Thus n = 0 defines an isobaric process, n = cp/cv an adia..
A Bead with a mass 10g can slide without friction on a circular motion massless hoop that is in a vertical plane and has a radius of 5 cm. The hoop rotates at a constant rate of 4rev/s about a vertical diameter.
A uniform electric field exists in the region among two oppositely charged plane parallel plates. A proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate, 1.65cm distant from the fir..
an engine has a hot reservoir temperature of 935 k and a cold reservoir temperature of 616 k. the engine operates at
A hot air balloon decends toward the ground with a velocity of (1.6 m/s). A champagne bottle is opened to celebrate takeoff, expelling the cork horizontally with a velocity of (4.0 m/s) relative to the balloon.
If a 2-mm diameter pellet is illuminated from the left and the right by laser beams, such with a diameter of 1 cm and a power of 1 megawatt, estime the pressure applied to the pellet, assume all the light that hits the pellet is absorbed.
Two different balls are rolled (without slipping) toward a common finish line. Their angular speeds are shown to the right. Find what angular speed would the losing ball have needed to cross the finish line at the same time as the winning ball
For a movie scene, an 80kg stuntman drops from a tree onto a 46kg sled that is moving on a frozen lake with a velocity of 10m/s toward the shore. find the speed of the sled after the stuntman is on board
why is the zeroth order maximum the same color as the source? for lines of a given order are the red or violet lines on
A disk of radius 12 cm, initially at rest, begins rotating about its axis with a constant angular acceleration of 8.1 rad/s2. Find the angular velocity of the disk
