Engineering hydraulics question

In summary, the problem involves finding the pressure at Point A, given the flow rate, distance, and height difference between Point A and Point B. The Bernoulli equation is used to simplify the problem, but the solution requires finding the velocity of the water first.

Homework Statement



Points A and B are separated by 3000 ft of new 6-in schedule-40 steel pipe. 800 gpm of 60 deg F of water flow from point A to point B. Point B is 60 ft above point A. What must be the pressure at Point A if the pressure at B must be 50 psig?


Homework Equations



PA/ρg + VA2/2g + ZA = PB/ρg + VB2/2g + ZB + hf
Since, VA = VB and ZA=0, Bernoulli equation can be simplified to:

PA/ρg = PB/ρg + ZB + hf

The Attempt at a Solution



I am stuck at this point if anyone can help I would greatly appreciate it

For Bernoulli you need V, so how would you go about finding V? If you had v you'd be home free, no?

(I assume 6" pipe means 6" diameter. And watch out for p given you as "psig").
 

1. What is hydraulics engineering?

Hydraulics engineering is a branch of engineering that focuses on the use of fluids, particularly water and oil, to generate and transmit power. It involves the design, construction, and maintenance of systems that use fluids to control and transmit forces.

2. What are some common applications of hydraulics engineering?

Hydraulics engineering has a wide range of applications, including in construction, manufacturing, transportation, and aerospace industries. Some common examples include hydraulic systems in heavy machinery, elevators, and braking systems in cars and airplanes.

3. How does a hydraulic system work?

A hydraulic system works by using a pump to push fluid through a closed circuit of pipes. The pump creates pressure, which forces the fluid to move and transmit forces to different parts of the system. Valves and actuators are used to control the flow of the fluid and convert the pressure into mechanical energy.

4. What are the advantages of using hydraulic systems?

Hydraulic systems offer several advantages, including high power density, precise control, and the ability to operate in harsh environments. They also have a long lifespan and require minimal maintenance compared to other systems.

5. What are some common challenges in hydraulics engineering?

One of the main challenges in hydraulics engineering is managing the potential hazards of working with high pressures and large volumes of fluids. Other challenges include maintaining system stability, preventing leaks and contamination, and ensuring proper maintenance and repairs.
