general price inflation is estimated to be 3% for the next 5 years, 5% the 5 years after that, and 8% the following five years. If you invest $10,000 at the market rate of 10% for those 15 years, what is the future worth at 15 years of your investment in then-current dollars and in year-0 dollars?
A stream is in equilibrium with atmospheric oxygen upstream of a waste outfall. The waste outfall creates a BODo of 20 mg/L in the stream. The k(BOD) is 0.4 /day and the k(o2) is 1.4 / day. The stream temperature is 15 degrees Celsius.
Constructing the foundation causes changes in the levels of vertical stress at all points in the soil. One such point lies at the centre of the footing plan and is at a depth of 10m. Determine the increment of vertical stress there.
determine the tangential component of the acceleration of the sled a) just before it reaches B, b) just after it passes C.
At a certain location on the surface of an engineering component, the material is in a state of plane stress with principal stresses of fmax = 150 MPa and fmin = 50 MPa (both tensile). If the yield strength of the material is Y = 350 MPa
Estimate the median and 90th percentile load of SS contained in the runoff. Note: COV = coefficient of variance
hydrogen is flowing in a 50 mm diameter pipe at a mass rate of 0.01 kg/s. at section 1 the pressure is 280 kPa abs and t= 25 . what is the average velocity?
An entrepreneurial new civil engineering graduate started a lab for testing endocrine disrupting compounds. The lab just broke even the first year, but in years 2 through 5, it made a profit of $97,000 each year.
Ball A is thrown vertically upward from the top of a 20-{\rm m}-high-building with an initial velocity of 3m/s . At the same instant another ball B is thrown upward from the ground with an initial velocity of 16m/s .
Water enters a two-armed lawn sprinkler along the vertical axis (normal to the page) at a rate of 80 L/s and leaves the sprinkler nozzles as 1.5-cm diameter jets at an angle of from the tangential direction.
The basic barometer can be used to measure the height of abuilding. If the barometric readings at the top and at the bottomof a building are 28.7 and 29.7 in Hg, respectively, determine the height of the building in feet.
The temperature = 25°C; assume that u = 10^-2 after the addition. Compare the value obtained when ionic strength effects are taken into account with that calculated when it is neglected.
If the amount of heat transfer in the HE unit is 2460 kJ per kg of steam, what is the magnitude of shaft work obtained from the turbine in kW?
