A 100-ft steel tape was used in the field to measure a distance of 247.53 ft. the following data represents the conditions in the field at the time of measurement: tempreture = 41 F, tension = 30 ib, and tape supported at ends only. the tape used in the field had a cross-sectional area of .009 in^2 and a weight of 2.5 ib. the tape was standrized at 68 F with a pull of 20 ib when supported throughout and was found to have a length of 99.983 ft. Determine the true horizontal legth of the distance measured in the field.
What is the settling velocity of a .5 micrometer silica sphere at 20 degrees Celsius and an ambient pressure of 150 kPa. The density of silica is 2600 kg/cubic meter.
A piece of corroded steel plate was found in a submerged ocean vessel. it was estimated that the original area of the plate was 62.5cm 2 and approximately 2.8k had corroded away during the submersion. Assuming a corrosion penetration rate of 5.1mm/yr..
Give the phase and the missing property of P, T, v and x. Put the values in a table withcolumns P, T, v, and x.
Aluminum cans in the 1970's were considerably heavier than they arenow. For a 0.355-L (12 oz) aluminum can, with mass 0.0205 kg, andusing a 25 percent recycling rate, find the primary energy requiredto produce the aluminum in one such can.
You have batched both of the mixes you designed in questions 6 and 7 on the same day and have made a sufficient number of 6" diameter and 4" diameter cylinders of each mix so that two cylinders of each size
knowing that the coefficient of static friction between the collar and the rod is .35, determine the range of values of p for which equilibrium is maintained when 0=50deg and M=20Nm
The 50mm radius pulley A of the clothes dryer rotates with an angular acceleration of (80^(1/2)A) rad/s, where angle A is in radians. Determine its angular acceleration when t= 2 , starting from rest.
After injecting 50 MMSCF (14.7 psia and 60 oF), the pressure increase from 2500 to 3500 psia. Deviation factors for the gas are 0.90 at 3500 and 0.80 at 2500 psia and the bottom-hole temperature is 160 oF. What is the cubic feet of gas storage spa..
Compare the stoichiometric air/fule ratios (AFR) for complete combustion of Benzene (C6 H6), Octane (C8 H8), and Ethanol (C2 H5 OH) in air (O2 + 3.76 N2). The only products should be CO2, H2O and N2.
Air enters an adiabatic nozzle at 4MPa and 400 K with a velocit of 25 m/s. Air at the exit is 2 MPa and a velocity of 160 m/s. Calculate entropy? Is this a reversable process?
A 300 acre parking lot has a runoff coefficient of 0.8 and a time of concentration of 40 minutes. Using the rational method (Q=CIA), what is peak Q if a 4"/hr rain falls for 10 minutes
A concrete sewer pipe 1m in diameter is laid so it has a drop in elevation of 30cm per 300m of length. If sewage (assume the properties are the same as those of water) flows at a depth of 50cm in the pipe,
