Liquid ethanol is a flammable fluid and can release vapors that form explosive mixtures at temperatures above its flashpoint at
marta [7]

Answer:

The volume flow rate necessary to keep the temperature of the ethanol in the pipe below its flashpoint should be greater than 1.574m^3/s

Explanation:

Q = MCp(T2 - T1)

Q (quantity of heat) = Power (P) × time (t)

Density (D) = Mass (M)/Volume (V)

M = DV

Therefore, Pt = DVCp(T2 - T1)

V/t (volume flow rate) = P/DCp(T2 - T1)

P = 20kW = 20×1000W = 20,000W, D(rho) = 789kg/m^3, Cp = 2.44J/kgK, T2 = 16.6°C = 16.6+273K = 289.6K, T1 = 10°C = 10+273K = 283K

Volume flow rate = 20,000/789×2.44(289.6-283) = 20,000/789×2.44×6.6 = 1.574m^3/s (this is the volume flow rate at the flashpoint temperature)

The volume flow rate necessary to keep the ethanol below its flashpoint temperature should be greater than 1.574m^3/s

ceramics must be heated in order to harden the clay and make it durable. the equipment used to heat the clay
SIZIF [17.4K]

Ceramics must be heated in order to harden the clay and make it durable. The tool used to heat the clay is called a Kiln.

<h3>What happens when ceramic is heated?</h3>

Cristobalite is a silica polymorph that is used in ceramics. Quartz particles in porcelain can change into cristobalite during burning. This has effects on the fired matrix's thermal expansion. When there is a high level of vitrification or a shape is unstable during the firing of ceramic ware, warping occurs.

Ceramic items are porous, brittle, and rigid. They are thus employed in the production of glass, ceramics, cement, and bricks. Additionally, ceramics are employed extensively in gas turbine engines. Artificial bones and dental implants are both made of bio-ceramics.

Any of the several tough, fragile, heat- and corrosion-resistant materials created by sculpting and then heating an inorganic, nonmetallic material like clay to a high temperature are known as ceramics.

In order to solidify the clay and make ceramics durable, heat must be applied. A kiln is the name of the device used to heat clay.

# line 1 age = int(input("Enter your age: ")) # line 3 print("Invalid input") If we want the computer to display "Invalid input"
user100 [1]

Answer:

Insert

'try:' at line 1

'except:' at line 3

Explanation:

The "try and except" commands in Python are used for exception handling.

try: the statements under this block are executed normally

except: the the statements under this block are executed when there is an exception.

We can use these commands to handle errors, for example, in the given scenario we don't want the user to enter a floating point number such as

1.5, 2.6 etc.

When the user enters an integer number then the except command is not executed.

When the user enters a floating point number then the except command is executed, program is stopped and error message is shown that is at line 4

Python code:  

# line 1

try:

# line 2

   age = int(input("Enter your age: "))

# line 3

except:

# line 4

   print("Invalid input")

Output:

Test 1:

Enter your age: 20

Test 2:

Enter your age: 20.5

Invalid input
