Akeystone pipeline has a diameter of 36 inches and a design flow rate of 590,000 barrels per day of crude oil at 40ºc. estimate the pump horsepower required if the length of the pipe is 1.9 mile(s). the pipe material is new steel. for crude oil at 40ºc, take μ ≈ 0.0053 kg/m-s ÷ 47.88 = 0.111 slug/ft-s. the density, with sg = 0.86, is 0.86(1.94) = 1.67 slug/ft3. round the answer to the nearest whole number. take f ≈ 0.0155.

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion

What is the power rating of the lightbulb if 3.0 a flow through it when connected to a 15 v battery

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
