3. Consider a 10-m-long smooth rectangular tube, with a = 50 mm and b=25 mm, that is maintained at a constant surface temperature. Liquid water enters the tube at 20C with a mass flow rate of 0.01 kg/s. Determine the tube surface temperature necessary to heat the water to the desired outlet temperature of 80C.

Calculate Original Oil in Place (OOIP). Suppose that from geological evidence it is known that the areal extent of an oil reservoir is 3 million sq. ft., the thickness of the pay zone (pay zone is the zone that contains producible hydrocarbons) is 40 ft., the porosity is equal to 30%, and Sw (water saturation) is 20%, and their is no Sg (free gas saturation).

Passband to baseband conversion: Consider the following passband signal,

ypt = V2sine (2t) cos (200mt).

where sinc (t) = / frac{sin (/pi t) }{/pi t} is the sinc function.

(1) What is the carrier frequency of y_{p} (t) ?

(2) What is the absolute passband bandwidth of y_{p} (t) ?

(3) Find the complex baseband equivalent y (t) of y_{p} (t).

(4) What is the absolute bandwidth of y (t) ?

A car is traveling up a 2% grade at 70 mi/h on good, wet pavement. The driver brakes to try to avoid hitting stopped traffic that is 250 ft ahead. The driver's reaction time is 0.5 s. At first, when the driver applies the brakes, a software flaw causes the antilock braking system to fail (brakes work in non-antilock mode with 80% efficiency), leaving 80 ft skid marks. After the 80 ft skid, the antilock brakes work with 100% efficiency. How fast will the driver be going when the stopped traffic is hit if the coefficient of rolling resistance is constant at 0.013? (Assume minimum theoretical stopping distance and ignore aerodynamic resistance.)

What advantage might there be to having the encoder located on the motor side of the gearhead instead of at the output shaft of the gearhead (in other words so that it would rotate at the speed of the armature rather than at the speed of the output shaft of the gearhead) ?
