Hello, everyone. I'll answer your questions. A host how to bring two monitors at the same time, a host how to use two monitors at the same time this many people do not know, now let's take a look at it!

Answer:

If you want to have two monitors on one computer, you must have support for a graphics card. There must be two or more different interfaces on the graphics card, both using hdmi and vga interfaces. Next, you need two monitors with hdmi and vga interfaces, and then connect the connectors of the graphics card to the computer monitor through the cable. After a successful connection, the computer system is accessed. In win7, for example, right-click in the white space of the desktop, select the screen resolution you want to turn on, and then select expand these displays among multiple displays.

2. The flow calculation formula is:

3. According to the test section and its velocity test results, the commonly used methods are graphic method, analytical method and velocity contour method. Graphic method and velocity contour method are only suitable for multi-line and multi-point flow measurement data, while analytical method is suitable for flow measurement data of various methods and widely used. According to the relevant formula of the analysis method, the discharge is calculated by calculating the average discharge on the vertical line, calculating the local area (average discharge and discharge), calculating the section area, section discharge and section average discharge, and calculating the corresponding water level. The main performance is that the cost is lower than the traditional cost when the usage is large, and how to choose the communication mode according to your own needs; the IP header length is 20 bytes, the TCP header length is also 20 bytes, a total of 40 bytes/piece, the protocol replies 40 bytes/packet terminal upload location, alarm and other information: The average value is 70 40 40=150 bytes/piece of terminal upload operation data, the average value is 110 40 40=190 bytes/piece of terminal reply scrambling information, and the average value is 72 40 40=152 bytes/piece. Average 72 40 40=152 bytes/piece of preemptive response information sent by the center, 100 40 40=180 bytes/piece of detailed scheduling information sent by the center, 120 40 40=200 bytes/piece of information.

This is the end of this article, I hope it helps everyone.
