Steam enters a diffuser at 20 psia and 240oF with a velocity of 900 ft/s and exits as saturated vapor at 240oF and 100 ft/s. The exit area of the diffuser is 1 ft2.
A tile-iron consists of a massive plate maintained at 150°C by an embedded electrical heater. The iron is placed in contact with a tile to soften the adhesive, allowing the tile to be easily
A large number of concrete slabs (each 0.6 m in length) are lined up with a spacing of 0.1 mm between them. The temperature is then increased by 50 °C.
Given the absolute roughness of the pipe is 0.26 mm, density of water is 998 kg/m3 and dynamic viscosity of water is 1.14 × 10-3 kgm 1s-1.
A remote sensing satellite is deployed in a circular sun-synchronous orbit with inclination 96.85°. A. Calculate orbit altitude (disregard gravitational pull by the Moon and Sun).
A total of 2.00 mol of a compound is allowed to react in a foam coffee cup that contains 138 g of water. The reaction caused the temperature of the water to rise from 21.0 to 24.7 C.
The two sides of a V-shaped water trough are hinged to each other at the bottom where they meet, as shown in Figure Q1 , making an angle of 45° with the ground from both sides.
The can diameter and height are D = 65 mm and H = 120 mm. The can is half-full of soda, with specific gravity SG = 1.06. Assume rigid body motion.
Hot air is contained in a vertical, frictionless piston-cylinder device.the piston has a mass of 4 kg and a cross-sectional area of 35 cm2. A compressed spring above the piston exerts a force of 4 N o
A valve connected to the cylinder is now opened, and air is allowed to escape until three-quarters of the mass leaves the cylinder at which point the volume is 0.05 m3.
Find a cylindrical container that is large enough that it takes at least one minute to drain (you may have to create an opening at or near the bottom that gives the right behavior.
The torsional assembly shown in Figure consists of a solid bronze (GB= 45 GPa)shaftCD and hollow aluminium alloy(GA=28 GPa) shaft EF that has a steel (Gs=80 GPa) core.
