MCHE
What is the 1st law of energy?
Energy cannot be created or destroyed, only transformed.
What does Ohm's law state?
voltage = current times resistance
CH3OH
What principle states that the sum of all forces and moments acting on a body must be 0?
What state sits on top of the largest oil reserve in the United States?
Texas
This simple machine consists of a wheel with a rope or cable wrapped around it and is commonly used to lift heavy loads by changing the direction of force
Pulley
Which component stores energy in a field and is measured in Farads?
Capacitor
One mole of an ideal gas at 300K is heated at a constant volume to 600K. By what factor does the pressure increase? (hint: PV=nRT)
2
This type of stress occurs when a structural member is being pulled apart
Tension
A. Crude oil is extracted and stored for future processing
B. Crude oil is separated into its individual components
C. Products such as polymers and gasses are created
In mechanics of materials, this bending equation relates normal stress in a beam to the bending moment, the distance from the neutral axis, and the area moment of inertia, commonly written as σ=My/I
Flexure Formula
What does a transformer do?
Hint: (increase, decrease)
Increases voltage in a power transmission system while decreasing current.
What is the name for the process of extracting individual components of crude oil via a Distillation column?
Fractionation
In structural analysis, this support condition allows rotation but prevents vertical and horizontal translation
Pinned (hinged) support
What is the called when high pressure fluid is inserted into earth to extract oil?
Fracking
This concept from the 2nd law of thermodynamics states measures unavailable energy in a system and always increases in an irreversible process
Entropy
What does Thevenin's Theorem do?
Hint: linear circuit
Simplifies a linear circuit into a single voltage source and series resistance
In heat exchangers, the rate of heat transfer is proportional to the temperature difference and surface area, and inversely proportional to this resistance to heat flow. What is the name of this property?
Thermal Resistance
This geotechnical failure occurs when shear stresses in soil exceed the soil’s shear strength, often analyzed using the Mohr-Coulomb criterion
Shear failure
In oil reservoirs, Darcy's Law states that flow rate through porous rock is proportional to pressure difference and permeability, and inversely proportional to this property of the fluid that resists flow. What is the name of the property of a fluid that resists flow?
Viscosity
In mechanics of materials, this property is defined as the ratio of normal stress to normal strain within the elastic region of a material and is commonly denoted by E
Young's Modulus
This dimensionless parameter determines whether a feedback amplifier will oscillate; sustained oscillations occur when the loop gain has magnitude equal to one and a phase shift of 0° (or 360°)
Barkhausen stability criterion
In reactor design, this ideal reactor model assumes perfect mixing such that the exit stream has the same composition and temperature as the contents inside.
Continuous Stirred-Tank Reactor
This failure mode in columns occurs when compressive stress causes sudden lateral deflection, described by Euler’s critical load formula
Buckling
This equation, commonly used in reservoir engineering, relates flow rate through porous media to pressure drop, permeability, viscosity, and cross-sectional area
