Bullet A from west with a mass of 175g and speed of 550m/s and bullet B from east with a mass of 150g and speed of 200m/s moves towards to a block that having mass 12kg. If the bullets stick to the block and they move together find the velocity of the final system and find the total impulse of each bullet if the movement takes 0.5s before coming to a stop.
The heat transfer convection coefficient between the wall and the fluid is 500 W/m2.K. Find the maximum temperature in wall.
approximately how many pounds of downward pressure is placed on a piston in an internal combustion engine at the moment of ignition? I know this will vary some depending on the type fuel, the size of the combustion chamber and ect.
Evaluate the effect of the water spray on efficiency (net work out divided by heat input) and net power out per kg/s of dry air coming into the turbine.
With reference to basic constructional features, contrast the methods of compression employed by positive displacement and dynamic air compressors.
Calculate the torque on each of the two shafts,the power transmitted and the power lost in friction. U=0.3 what is the efficiency of the drive.
Why do thermoplastics tend to become brittle in very cold weather?
A cylindrical specimen of this alloy 24 mm in diameter and 186 mm long is to be pulled in tension. Calculate the force necessary to cause a 0.0119 mm reduction in diameter. Assume a value of 0.33 for Poisson's ratio.
Calculate the mass flow (in slugs/per second) that comes out the exit of the engine. The plane is at standard altitude 50,000 ft and velocity = 2200 ft/s. Would appreciate attack to problem.
What is the discharge revised discharge pressure (guage pressure) of the compressor ? Is the assumption of change in temperature valid for calculating the discharge pressure of the compressor ?
