Ammonia vapor flows through a valve. It enters the valve at a pressure of 8 bar and a temperature of 120C and after going through a throttling process it exits at a pressure of 3.5 bar. What is the temperature of the vapor exiting the valve in C?
Determine the projected component of the force fac along the axis of strut ao. Express the result as a cartesian vector.
Explain how the different physical characteristics and moisture content of soil lead to the different angles of repose, swell, and shrinkage factors. Explain how these factors affect excavation operations and costs.
Water flows uniformly in a 6 m wide rectangular channel at a depth of 0.8m. The channel slope is 0.0015 and n=0.014. Find the flow rate in m3/s
The velocity distribution for water (20 C) near a wall is given by u=a(y/b)^1/6 where a=10m/s, b=2mm, and y is the distance from the wall in mm. Determine the shear stress in the water at y=1mm. [viscosity of water at 20 C = 1.81 x 10^-5]
