Steam enters a circular pipe at 1600 kPa, 400 oC and 10 m/sec and exits at 1000 kPa and 32 m/sec. The diameter of the pipe at the entrance is 15 cm. find parameters of steam and pipe. ( correct solution needed very urgent.)
Density-Gravity Problem: a) Planet Vulcan has twice the mass of Earth and the same radius. What are its volume, density and surface gravity compared to Earth?
A somewhat longer cable replaces the old and is attached to the steel bar 5 m from its upper end, connecting to the same place on the wall as before and maintaining the same angle between the bar and the wall.
A copper wire has diameter 0.140mm and length 11.0cm . It's in a horizontal plane and carries a current of 2.50A, Find the magnitude of the magnetic field needed to suspend the wire against gravity.
Four objects are situated along the x axis as follows: a 1.70kg object is at -0.9m, a 1.60kg object is at 0.2m, a 2.4-kg object is at the origin, and a 2.50kg object is at -1.10m.
Explain how fast would it be moving after it had fallen a distance of 0.010 m? (Assume that the gravitational force is constant over the distance of the fall, and that the star is not rotating.)
A Carnot engine performs work at the rate of 480 kW as using 640 kcal of heat per second. If the temperature of the heat source is 540°C, at what temperature is the waste heat exhausted.
A 4.0 kg block is released from rest at the top of a 30 degree frictionless incline. The block makes a head on elastic collision with another 3.0 kg block initially at rest on a horizontal surface at the bottom of the incline.
If the mass of both weights is 175gm, the first mass is located 20 north of east, the second mass is located 20 south of east, and the transducer sensitivity is 0.5volts/Newton, how large a voltage do you expect to measure? Imagine the transducer ..
Find out the magnetic force on the rod
A 2.1-kg block is released from rest and allowed to slide down a frictionless surface and into a spring. The far end of the spring is attached to a wall, as shown. The initial height of the block is 0.36 m above the lowest part of the slide and the s..
An ac generator has a circular coil of 338 turns and diameter 0.200 m which rotates about an axis in the plane of the coil, What is the peak emf (in V) generated across the generator coil
Suppose an asteroid is found that appears to be heading directly toward Earth (using Earth's location at the time of discovery). It is 4.2 A.U. away (i.e., 4.2 times the Earth-Sun distance), and travelling through the Solar System with a speed of ..
