A cue stick exerts a force of 200 N for 10?3 s to a stationary billiard ball (A) with mass m. Then this billiard ball (A) hits another billiard ball (B) with same mass and which is at rest initially. After the collision, the billiard ball (B) moves with a speed vB = p 2 m/s at an angle 45 degree with respect to the axis of the incoming ball (A). Assuming no friction between the billiard balls and the...

Problem #3: Biochemical Oxygen Demand (BOD) and Stream Quality A wastewater treatment plant designed for a community of 45,000 people has a flow of 100 gal/person/day and a BOD5 loading of 0.2 lb/person/day. The upstream characteristics of the receiving waters are: stream flow rate = 20 cfs and BOD5 = 2 mg/L The water quality standards require the in-stream BOD5 to be less than 7 mg/L in this stretch of the river. The minimum BOD removal efficiency that the treatment...

City water will be cooled in a heat exchanger by sea water entering at 15°C. The outlet temperature of the sea water is 20°C. City water will be recirculated to reduce water consumption. The suction line of the pump has an inner diameter of 154 mm, is 22 m long, and has two 90° bends and a hinged check valve. The pipe from the pump to the heat exchanger has an inner diameter of 127 mm, is 140 m long,...

1) A nozzle is a device for increasing the velocity of a steadily flowing stream of fluid. At the inlet to a certain nozzle the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s. At the exit from the nozzle the enthalpy is 2790 kJ/kg. The nozzle is horizontal and there is negligible heat loss from it. (i) Find the velocity at the nozzle exit. (ii) If the inlet area is 0.1 m2 and specific volume...

Five years ago, Kennedy Trucking Company was considering the purchase of 60 new diesel trucks that were 15% more fuel-efficient than the ones the firm was using. Mr. Hoffman, the president, had found that the company uses an average of 10million gallons of diesel fuel per year at a price of $1.25 per gallon. If he can cut fuel consumption by 15%, he will save $1,875,000 per year (1,500,000 gallons times $1.25). Mr. Hoffman assumed that the price of diesel...

#1. A street light is supported by two wires and each makes a different angle from each other. The one on the left is 32 degrees and the one on the right is 43 degrees. Find the tension in each wire if the street light has a mass of 60.0 kg. #2. There are three masses: m1 = 2.0 kg, m2 = 5.0 kg and m3 = 7.0 kg. The masses are all affixed to a massless rod of length...
