Assume that a gallon of gas contains 114,000 BTUs of energy and that a brilliant engineer has created an 80 percent efficient solar cell. Find the area (in square smoots and in square feet) that an array of these solar cells would need to power the average car (3 gallons of gas per hour). Use 1.361 as the value for the solar constant. You will need to google "solar constant" to obtain the correct units.
Calculate the stress at failure of a concrete test cylinder with a measured diameter of 152.4 mm and a recorded load of 371,426N. Units of ksi.
An engineering student, recognizing that the "ideal gas law" requires gas velocity to be function of temperature, suggests that an easy way to increase efficiency would be to change the temperature of the exhaust gas being treated.
A new development is to be constructed in Mexico City. Due to the large subsidence, the elevation at the proposed site must be raised prior to construction. The total volume of soil needed to raise the site is 100,000 cubic yards.
For each of the two cases below, determine the water pressure, pressure head, elevation head, and total head at points A, B, and C. Please solve the problem using: (a) the upper reservoir level as the datum
How much calcium bicarbonate (kg/day) will need to be added per day in water with alkalinity of 30 mg/L CaCO3 to prevent rapid pH decrease (assume for simplicity inly bicarbonate alkalinity is present) if 794 kg of Al2(SO4)3 x 18H2O
An aerosol with a lognormal size distribution has a count median diameter of 2.0 micron and a geometric standard deviation of 2.2. If the mass concentration is 1 mg/cubic meter what is the number concentration
A tubular aluminium bar (G=28GPa) of square cross section with outer dimensions 50mm x 50mm must resist a torque T=300Nm. Calculate the minimum required wall thickness t_min if allowbale shear stress is 20MPa
A confined aquifer has a specific storage of 2.5 * 10^-6 /m . The porosity is .20 and the water compressibility is 5 * 10-10/Pa.For the aquifer skeleton compressibility you just calculated, what would the aquifer specific storage be if porosity were ..
The transportation agency would like to determine the maximum spacing of stations to allow trains to arrive no more than 5 minutes apart. 1. Draw a time-space diagram depicting the above scenario
The two shafts in a speed-reducer unit are subjected to couples of magnitude M1 = 18 N · m and M2 = 7.5 N · m, respectively.
A small building that shelters a water supply pump measures 2 m x 3 m x 2.4 m high. It is constructed of 1- cm thick wood having a thermal conductivity of 0.126 W*m^-1*K^-1.
If there are 50 vehicles on a 4000-ft highway lane and the average time headway between two adjacent vehicles is 2.2 seconds. A) Calculate traffic density in vehicle/mile (vpm) and average space headway in feet/vehicle (fpv).
