The pressure difference, across a partial blockage in an artery (called a stenosis) is approximated by the equation Δp= Kv. μV/D + Ku (Ao/A1- 1)^2. rhoV^2

where V is the blood velocity, μ the blood viscosity p the blood density the artery diameter, the area of the unobstructed artery, and A1 the area of the stenosis. Determine the dimensions of the constants and Would this equation be valid in any system of units?

On a average work day more than work place firs are reorted

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
