Water at 15°c (rho = 999.1 kg/m3 and μ = 1.138 × 10−3 kg/m·s) is flowing steadily in a 29-m-long and 6-cm-diameter horizontal pipe made of stainless steel at a rate of 10 l/s. determine the pressure drop, the head loss, and the pumping power requirement to overcome this pressure drop. the roughness of stainless steel is 0.002 mm.

Aferris wheel is a vertical, circular amusement ride with radius 9 m. riders sit on seats that swivel to remain horizontal. the ferris wheel rotates at a constant rate, going around once in 9 s. consider a rider whose mass is 56 kg. at the bottom of the ride, what is the perpendicular component of the rate of change of the rider's momentum? at the bottom of the ride, what is the vector force exerted by the seat on the rider?

Asystematic approach to problem solving is called a (an)
