The laboratory apparatus we used to measure hydrostatic forces is shown below.
a) Derive the formula for ''W'' as a function of ''h''.
b) Plot h versus W. Use the actual values that we used during the lab session for L, Y and b.
Consider a prevailing lapse rate that has these temperatures: ground=21C, 500m= 20C, 600m= 19C, 1000m= 20C.If a parcel of air is released at 500m and at 20C, would it tend to sink, rise or remain where it is
The golf ball has a diameter of 1.70 in and weighs 0.099 lb. Assuming standard atmospheric conditions (mu, u air = 3.74 * 10^-7 lb-s/ft2 and rho = 0.00238 slug/ft3)
Incandescent light bulbs have been phased out in the US because they are very inefficient (i.e., they produce a very large amount of heat). A 10 W light-emitting diode lamp (LED) can produce about the same light output as incandescent light bulbs
A closed tank having a volume of 1.0 ft3 is filled with 0.15 lb of a gas. A pressure gage attached to the tank reads 12 psi when the gas temperature is 80 F. There is some question as to whether the gas in the tank is oxygen or helium.
To cross a river that is 1 km wide, with a current of 6km/h, a novice boatskipper holds the bow of the boat perpindicularto the far river bank, intending to cross to a point directly across the river from the launch point.
The moment of inertia of the footing about its diameter is piB^4/64. What would be the maximum eccentricity such that the entire soil beneath the footing is in compression FOr this value of eccentricity, draw the pressure distribution around the p..
Nitrate concentrations are often recorded in units of NO3--N/L to be compared with other nitrogen constituents. Near three rural wells nitrate concentrations were reported as 0.25 mg
Air enters an adiabatic nozzle steadily at 300 kPa, 200?C, and 30 m/s and leaves at 100 kPa and 180 m/s. The inlet area of the nozzle is 80 cm2. Determine (a) the mass flow raw through the nozzle, (b) the exit temperature of the air, and (c) the e..
A tank is filled with oil (specific gravity 0.8) and water to a depth of 10 meter and 6 meter respectively. Find the resultant force from all fluids acting on the gate of 1.8 meter by 9 meter.
Offer an explanation as to why covalently bonded materials are generally less dense than ionically or metallically bonded ones.
What are the differences between airborne infectious diseases and diseases that are caused by air pollution? Give at least two examples for each category of diseases.
The slope distances shown were measured with an EDM while the differences in elevation between the ends of each line were determined by leveling. What are the horizontal distances
