A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 43.0cm wide and 51.6cm high. The maximum safe pressure inside the vessel has been measured to be 6.90MPa.For a certain reaction the vessel may contain up to 5.26kg of dinitrogen difluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Be sure your answer has the correct number of significant digits.

Expert Answer

Step 1

Given that,

Pressure inside the vessel is 6.9 MPa

Height of the cylinder is 51.6 cm

Wide of the cylinder is 43.0 cm

Step 2

Now you calculate the Volume of cylinder

V=jur2h
where r is the radius of the cylinder
