Telnet into a Web server and send a multiline request message. Include in the request message the If-modified-since: header line
to force a response message with the 304 Not Modified status code.
1 answer:
Answer:
The following command is issued
in Windows command prompt
followed by the HTTP GET
message to the “utopia.poly.edu"
web server:
> telnet utopia.poly.edu 80
As the index.html page in the web
server was not modified since
Mon, 18 May 2015 09:23:34GMT,
the following outputwas displayed
when the above commands were
issued on Sat, 23 May 2015.
The first 4 lines are the GET
message and header lines input by
the user.
The next 4 lines (starting from
HTTP/1.1 304 Not Modified) are
the response from the web server.

Explanation:
= Area of section 1 =
= Velocity of water at section 1 = 100 ft/min
= Specific volume at section 1 =
= Density of fluid =
= Area of section 2 =
Mass flow rate is given by
The mass flow rate through the pipe is
As the mass flowing through the pipe is conserved we know that the mass flow rate at section 2 will be the same as section 1
The speed at section 2 is .
Answer:
5.6 mm
Explanation:
Given that:
A cylindrical tank is required to contain a:
Gage Pressure P = 560 kPa
Allowable normal stress = 150 MPa = 150000 Kpa.
The inner diameter of the tank = 3 m
In a closed cylinder there exist both the circumferential stress and the longitudinal stress.
Circumferential stress
Making thickness t the subject; we have
t = 0.0056 m
t = 5.6 mm
For longitudinal stress.
t = 0.0028 mm
t = 2.8 mm
From the above circumferential stress and longitudinal stress; the stress with the higher value will be considered ; which is circumferential stress and it's minimum value with the maximum thickness = 5.6 mm
