El agua fluye hacia abajo a lo largo de una tubería que está inclinada 30 por debajo de la horizontal, como se muestra. La diferencia de presión pA 2 pB se debe en parte a la gravedad y en parte a la fricción. Derive una expresión algebraica para la diferencia de presión. Evalúe la diferencia de presión si L = 5 pies y h = 6 pulg.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa. s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false
