4. Calculate the bottomhole pressure for the injection of 1500 bbl/d of brine with a density of 1.08 g/cm3 and a viscosity of 1.3 cp in an 8000-ft vertical well having a surface pressure of 200 psi and (a) 2-in., 3.4-lbm/ft tubing; (b) 2 7/8-in., 8.6-lbm/ft tubing; (c) 3 1/2-inch, 12.70-lbm/ft tubing.

d.7.5cm is your answer

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
