Answer:
F = 8552.7N
Explanation:
We need first our values, that are,
![V_{jet} = 40m/s\\V_{Plate} = 10m/s \\D = 11cm](https://tex.z-dn.net/?f=V_%7Bjet%7D%20%3D%2040m%2Fs%5C%5CV_%7BPlate%7D%20%3D%2010m%2Fs%20%5C%5CD%20%3D%2011cm)
We start to calculate the relative velocity, that is,
![V_r = V_{jet}-V_{plate}\\V_r = (40)-(10)\\V_r = 30m/s](https://tex.z-dn.net/?f=V_r%20%3D%20V_%7Bjet%7D-V_%7Bplate%7D%5C%5CV_r%20%3D%20%2840%29-%2810%29%5C%5CV_r%20%3D%2030m%2Fs)
With the relative velocity we can calculate the mass flow rate, given by,
![\dot{m}_r = \rho A V_r](https://tex.z-dn.net/?f=%5Cdot%7Bm%7D_r%20%3D%20%5Crho%20A%20V_r)
![\dot{m}_r = (1000)(30) \frac{\pi (0.11)^2}{4}](https://tex.z-dn.net/?f=%5Cdot%7Bm%7D_r%20%3D%20%281000%29%2830%29%20%5Cfrac%7B%5Cpi%20%280.11%29%5E2%7D%7B4%7D)
![\dot{m}_r = 285.09kg/s](https://tex.z-dn.net/?f=%5Cdot%7Bm%7D_r%20%3D%20285.09kg%2Fs)
We need to define the Force in the direction of the flow,
![\sum\vec{F} = \sum_{out} \beta\dot{m}\vec{V} - \sum_{in} \beta\dot{m} \vec{V}\\](https://tex.z-dn.net/?f=%5Csum%5Cvec%7BF%7D%20%3D%20%5Csum_%7Bout%7D%20%5Cbeta%5Cdot%7Bm%7D%5Cvec%7BV%7D%20-%20%5Csum_%7Bin%7D%20%5Cbeta%5Cdot%7Bm%7D%20%5Cvec%7BV%7D%5C%5C)
![F = \dot{m}V_r](https://tex.z-dn.net/?f=F%20%3D%20%5Cdot%7Bm%7DV_r)
![F = (285.09Kg/s)(30)](https://tex.z-dn.net/?f=F%20%3D%20%28285.09Kg%2Fs%29%2830%29)
![F = 8552.7N](https://tex.z-dn.net/?f=F%20%3D%208552.7N)
Any collection of data or information that has been properly structured for quick search and retrieval by a computer is referred to as a database, often known as an electronic database.
<h3>What is electronic database?</h3>
- Databases are designed to make it easy to save, retrieve, edit, and delete data while carrying out various data-processing tasks. In response to queries, a database management system (DBMS) retrieves data from the database.
- Databases are briefly discussed after that. See computer science: Information systems and databases; information processing for a comprehensive explanation.
- A file or collection of files used to store a database.
- These files' contents can be divided up into records, each of which has one or more fields.
- The fundamental units of data storage are fields, and each field typically contains data related to one feature or attribute of the thing that the database is describing.
- Additionally, records are arranged into tables that contain details on the connections between their various fields.
- A database in the strict sense offers cross-referencing capabilities, despite the fact that the term "database" is used broadly to refer to any collection of information in computer files.
- Users can quickly search, rearrange, organize, and choose the fields in numerous records to access or produce reports on certain data aggregates using keywords and a variety of sorting instructions.
