A Brayton cold ASC has a turbine that is 80.0% isentropically efficient and a compressor with an isentropic pressure ratio of 7.00. The compressor inlet temperature is 530. R and the turbine inlet temperature is 2460 R.
Determine the compressor isentropic efficiency that causes the entire cycle thermal efficiency to become exactly zero. Assume k = 1.40.
a particle of mass m is confined to a tube of length l.a use the uncertainty principle to estimate the smallest
A simple pendulum makes 137 complete oscillations in 3.20 min at a location where g = 9.80 m/s2. Find the period of the pendulum.
A frictionless ramp is constructed so that it is at a 30 degree angle to the horizontal. It is 1.8 meters long and 0.9 meters high. How far along the rough patch do the blocks go before stopping
A 5 kilogram weight is pushed up a 30 degree incline for 10.0 minute with a 98.0 Newton force parallel to the plane. Find what is the velocity of the weight after having been pushed the 10.0 m
When a pitcher throws a curve ball, the ball is given a fairly rapid spin. If a 0.15-kg baseball with a radius of 3.7cm is thrown with a linear speed of 48 m/s and an angular speed of 42 rad/s, how much of its kinetic energy is translational and how..
Two different balls are rolled (without slipping) toward a common finish line. Their angular speeds are shown to the right. determine how long does each ball take to reach the finish line
