g column of sand has water flowing through it. At the left end of the column, the pressure is 37,470 Pa, and the elevation is 0.310 m. At the right end of the column, the pressure is 26,820 Pa, and the elevation is 0.260 m. The permeability of the sand is 2.07 x 10-13 m2. The internal diameter of the column is 0.0100 m, and the column is 1.05 m long. Total porosity is 0.21. Effective porosity is 0.18. How long will it take for a sorbing tracer with R

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
