Argon gas enters a constant cross-sectional-area duct at Ma1= 0.2, P1= 320 kPa, and T1 =400 K at a rate of 0.8 kg/s. Disregarding frictional losses, determine the highest rate of heat transfer to the argon without reducing the mass flow rate.
Devise an absolute temperature scale where the boiling point of water at 1 atmosphere (101 kPa) pressure = 100 degrees in your scale What is the ice point of water in your scale?
Explain, in some detail, the design conditions and shear strengths used for each design condition when working with clay soils?
a level is setup midway between X and Y reads 5.572 ft on X and 4.946 ft. on Y. The level is setup very close to X and a reading of 4.666 ft. is taken on X. what should the reading be at Y to adjust any collimation error of the level
(i) Determine the flow rate through pipe B. Discard minor losses and assume the water temperature to be 150C. (ii) Show that the flow is fully rough and thus the friction factor is independent of Reynolds number.
A cylindrical pressure tank has internal dimensions of 14.0 inches diameter, and 36 inches length from end to end. Max. recommended pressure at 70degF is 200 PSI. The cylinder has a safety relief valve which is set at 250 PSI.
It is desirable to produce a copper-nickel alloythat has a minimum noncold-worked tensile strength of 380 MPa(55,000 psi) and a ductility of at least 45% EL. Is such an alloypossible? If so, what must be its composition? If this is notpossible, then ..
A 50-kg iron block at 80C os dropped into an insulated tank that contains 0.5m^3 of liquid water at 25C. determine the temperature when thermal equilibrium is reached.
The flat circular disk rotates about a vertical axis through O with a slowly increasing angular velocity ?. Prior to rotation, each of the 0.60-kg sliding blocks has the position x = 29 mm with no force in its attached spring. Each spring has a stiff..
Water is flowing in a trapezoidal channel with 10 ft bottom width and 2H/IV side slopes. The channel is running on a slope of 0.00778 ft/ft and the flow exerts a shear stress of 1.5 lbs/ft2 on the channel bed. What is the depth of flow in this cas..
Body A and body B are connected by an inextensible cord. If both bodies are released simultaneously from rest, what distance do they move in 3 sec and what is the tension in the cord. The weight of A is 50 lb and the weight of B is 10 lb.
A fireman reduces the exit area on a nozzle so that the velocity inside the hose is quite small relative to the exiting velocity. What is the maximum exiting velocity and what is the maximum height
Assume frictionless flow in a long, horizontal, conical pipe. The diameter is 12 inches at one end and 6 inches at the other. The pressure head at the smaller end is 16 feet of water.
