The flowrate Q over a rectangular sharp crested weir depends on the width of the notch b, the head on the weir H, and the acceleration due to gravity g.Find how many dimensionless parameters govern this problem. Use dimensional analysis to find the relationship.
The cars have equal mass. Car A is suddenly given velocity 4 m/s and the rope becomes taut. We know that 40 percent of the system's kinetic energy is lost during the rope tensioning.
Blood is flowing through an aorta of 1.0 cm diameter at an average velocity of 50 cm/s. The mean pressure is 100 mm Hg, The blood enters a stenosis where the aortic diameter is 0.5 cm. What is the appropriate pressure at the point of maximum steno..

The drag force (Fd) acting on a spherical particle that falls very slowly though a viscous fluid is a function of a particle diameter, d, the particle velocity, V, and the fluid viscosity, u.
The water table is at a depth of 1 m. Compute the effective normal stress and the shear stress acting on a plane rotated 60 degrees clockwise from the horizontal at a depth of 2.5 m in this deposit.
A larger-diameter pipeline will cost $2.1 million installed, but its operating cost will be only $8000 per month. Which pipe size is more economical at an interest rate of 1% per month on the basis of an annual worth analysis
A 500 L (132 gal) tank contains 255 mg/L 2,4,6-trichlorophenol dissolved in trichloroethylene (TCE). What is the 2,4,6-trichlorophenol concentration in ppm Assume the temperature of the system is 20 degrees C.
A truck is designed to measure concrete roughness. During a typical test the driver will bring the vehicle to a constant test velocity, v, and then suddenly lock the brakes bringing the vehicle to a complete stop.
A typical propane tank that we use for barbeque initially contains a pressure of 10 psi. The pressure is low, so we take it to the local store to fill the tank with more propane. After filling,the pressure is 100 psi.
Locate the image using both the spherical mirror equation and a ray diagram and identify if it is real or virtual, upright or inverted, and smaller or larger.
