A fire hydrant is supplied through a 6 inch cast iron pipe of 16,000 feet length. The total drop in pressure is limited to 35 psi. What is the discharge through the pipe for a water temperature of 80°F ((kinematic viscosity) = 0.93 × 10-5 ft2/sec)? i) Apply the Darcy-Weisbach equation, and ii) apply the Hazen-Williams equation.
Calculate the volume of a cylinder that contains 60 lbm of carbon dioxide at 230°F and 23 psig pressure. Assume atmospheric pressure to be 14.7 psia.^4
The volume of the system is doubled from 1 m^3 to 2 m^3 while 200 kJ of heat is added to the system. If no work is done except for the boundary displacement work and the pressure remains constant at 101.3 kPa (1 atm) throughout the process,
The arrival rate at a parking lot is 6 veh/ min. Vehicles start arriving at 6: 00 P. M., and when the queue reaches 36 vehicles, service begins. If company policy is that total vehicle delay should be equal to 500 veh-min
A Carnot heat engine is supplied with a high temperature heat source at a rate of 200 kW. If the power output of the heat engine is 120 kW, determine the required source temperature if the heat sink temperature is 20 °C.
a spherical balloon is being inflated so that its volume is increasing at the rate of 5 cu meter/min. at what rate is the diameter increasing when the diameter is 12m?
if the aircraft is encountering a steady side wind of speed vw=10 mi/hr , at what angle (a) should the pilot direct the aircraft so that the absolute velocity is parallel to the runway
What is the concentration (M) of Al3+ in lake water with pH = 4 assuming the equilibrium below with excess Al(OH)3 (s) The reaction is Al(OH)3 (s) --> Al3+ + 3OH-. pKsp = 32.9.
two sedimentation tanks operate in parallel. The combined flow to the two tanks is .1 m^3/s. the depth of each tank is 2 m and each has a detention time of 4 h.
Car B is driving straight toward the point O at a constant speed v. An observer, located at A, tracts the car with a radar gun. What is the speed |r(dot)B/A| that the observer at A records
Assume that you have a constant diameter pipe that has no pumps or turbines connected to it.Prove that the fluid in the pipe will flow from a location with high piezometric pressure to one with low piezometric pressure.
The grains of wood in the board make an angle of 20 degrees with the horizontal as shown. Determine the normal and shear stresses that act perpendicular and parallel to the grains if the board is subjected to an axial load of 250 N.(Dimensions l=3..
The machine part ABC is supported by a frictionless hinge at B and a wedge at C. Knowing that the coefficient of static friction is 0.20 at both surfaces of the wedge, determine:
