Consider the steady viscous flow through a small horizontal tube. for this type of flow, the pressure gradient along the tube should be a function of the dynamic viscosity, the mean velocity and the diameter of the tube. use dimensional analysis to derive a formula relating these variables.
The gasoline at point C and time t has an acceleration given by a=(-12i+40k) ft/s^2 where i and k are the horizontal and vertical unit vectors. Find the rate of increase of the piezometric head and the pressure in the x,y,z and a directions.
A waste heat source is available at 400°C. A heat engine operates using heat from this source. It rejects heat to the surroundings at 38°C. The power from the engine runs an air conditioner to keep the air inside a building at 25°C
Your engineering consulting firm has been asked to determine the specific weight of an unknown material. You decide to use the concept of buoyancy to figure this out. So you weigh the material in both air and water.
A supervisor is sitting at her desk illuminated by a 180 candela source 3 feet above it. She is writing with green ink (reflectance=30%) on a yellow note pad (reflectance=60%). What is the illumination on the note pad?
The coefficient of volume compressibility is 4x10-4 m2/kN at the ground surface and the reduction in the coefficient of volume compressibility with depth equals depth*0.1*10-4 m2/kN.
A pressure cooker maintains a constant pressure while food cooks in a water-steam mixture. If the pressure is higher than atmospheric, the water in the cooker boils at a higher temperature and makes cooking faster.
The pollutant has a reaction rate coeeficient k of 0.25/day. Assuming is pollutant is well mixed in the lake, find the steady-state concentration of pollutant in the lake.
The plate OAB forms an equilateral triangle which rotates counterclockwise with increasing speed about point O. If the normal and tangential components of acceleration of the centroid C
To determine the original length of a slender rod given the normal strain and deformation experienced by the rod due to an applied axial load. rod AB is subjected to the loading of two blocks, each of weight W
The fermenter stream you saw for the last problem is to be separated by distillation as shown below. Its composition is 85.0 mol % water (H2O, MW = 18.01), 10.0 mole % ethanol (C2H5OH, MW = 46.07), and 5.0 mol % sucrose
Determine suitable footing dimensions to suit the bearing capacity of 100kPa with a factor of safety 2.4
A tracer dye is injected into a 55-ft thick sandy gravel confined aquifer which has a hydraulic conductivity of 1.2 x 10^-3 ft/s. The dye appears 14 days later in an observation well 75 ft away from the injection point.
