Objective: a) To determine the coefficient of discharge for a Venturi meter. b) To investigate the variation of piezometer (or static) head along the length of the Venturi meter. Theory: A venturi is a short tube with a constricted throat used to determine fluid pressure and velocities by measurement of differential pressures generated at the throat as fluid transverses the tube. It was by this method the venturi meter was develop by a scientist known as Clemens Herschel. [pic]

Questions 5 Objective: The objective of this lab is to configure DNS client settings, for Linux and Windows Stations, to observe DNS in action, and to observe NAT in action. Procedures: 1. First, verify that workstation 1 and workstation 2 have the correct IP addresses and default route. 2. Configure DNS servers for workstation 1 and workstation 2. After, configure workstation 2 to use 131.94.131.43 as a DNS resolver by entering the command: echo “nameserver 131.94.133.43” >

free pseudo web site so you can get word press, because you won’t have your own domain name you would be part of word press. The DNS is completely hidden within the internet. If you ever sent an e-mail you used DNS, or even the URL has the domain name in it. You would still need an IP address, because every time we use a domain name, we will use the internet’s DNS to translate the domain name into the machine readable IP address. Anyone on line uses hundreds of domain name servers and don’t know
