Water is pumped from a large reservoir to a point 75 feet higher
than the reservoir. How many feet of head must be added by the
pump if 7600 lbm/hr flows through a 6-inch pipe and the frictional
head loss is 3 feet? The density of the fluid is 60 lbm/ft³ and the
pump efficiency is 70%. Assume the kinetic energy correction
factor equals 1.
A firefighter is using a large water tank to supply water for extinguishing a fire. The
tank has a small hole at the bottom, and water is leaking out due to gravity. The
hole is located 2.5 meters below the water surface inside the tank.
a. Determine the speed at which the water exits the hole. Assume there is no air
resistance and that the water flow is ideal (neglect viscosity and turbulence).
b. If the hole has a diameter of 2 cm, calculate the flow rate (discharge rate) in
liters per second.

- Answer the questionsarrow_forwardFigure below shows a portion of a fire protection system in which apump draws water at 60 F from a reservoir and delivers it to point B at the flow rate of 1500 gal/min a). Calculate the required height of the water level in the tank in order to maintain 5.0 psig pressure at point A. Answer: h = 12,6 ft b). Assuming that the pressure at A is 5.0 psig, calculate the power delivered by the pump to the water in order to maintain the pressure at point B at 85 kPa. Include energy lost due to friction but neglect any other energy losses. P₁ =19,2 hparrow_forwardWater at 60° F is being pumped from a stream to a reservoir whose surface is 210 ft above the pump.

- Hydrogenation of Ethylbenzene to Styrene Reaction: C₈H₁₀ → C₈H₈ + H₂ΔHᵣ°(300°C) = -124 kJ/mol (exact value unknown) Process Description: The basis is 1000 kg/h of separated styrene. The reaction conversion rate is 35%. The temperature increase in heat exchanger 2 is adiabatic. A fresh stream of pure ethylbenzene (25°C) enters a mixing vessel, where it is combined with a recycle stream (from the distillation column, as explained later), which also consists of pure ethylbenzene at 25°C. After mixing, the stream is sent to a heat exchanger (HX1), where the mixture is heated to 200°C. Next, the mixture enters an adiabatic heat exchanger (HX2), where it is further heated to 300°C by adding steam (at 350°C). This steam is used to prevent side reactions and carbon deposition in the reactor. The heated mixture is then fed into the reactor, where the reaction takes place with a conversion rate of 35%. As a result, the mixture cools down to 260°C. The resulting mixture is then sent to HX4, where…arrow_forwardChemical Engineering Questionarrow_forward4.5arrow_forward
