How do you avoid porosity in casting? The most economical and successful approach to stop casting porosity is through vacuum impregnation. Vacuum impregnation is a method that seals the casting resulting from porosity. The impregnating sealant is introduced into the voids within the wall thickness of the casting through vacuum and/or pressure methods. What are […]
How do you classify soil using Aashto?
How do you classify soil using Aashto? The AASHTO system uses both grain-size distribution and Atterberg limits data to assign a group classification and a group index to the soil. The group classification ranges from A-1 (best soils) to A-8 (worst soils). Group index values near 0 indicate good soils, while values of 20 or […]

Why is paying the minimum balance on a credit card a bad idea?
Why is paying the minimum balance on a credit card a bad idea? Because it takes so long to pay off your balance when you’re paying the minimum on your credit card, interest builds up longer. Credit card companies set the minimum low to maximize the interest they earn on your account. When you make […]
Which are the mixture used to make acetylene gas?
Which are the mixture used to make acetylene gas? It is created by mixing lime and coke in a blast furnace. The product manufactured is calcium carbide. It is reacted with water to create acetylene gas, and this reaction can be easily formulated as CaC2 + 2H2O → C2H2 + Ca (OH)2. Acetylene, calcium hydroxide […]
Which dimensionless number is used in forced convection?
Which dimensionless number is used in forced convection? In forced convection the Reynolds number governs the fluid flow. But, in natural convection the Grashof number is the dimensionless parameter that governs the fluid flow. Using the energy equation and the buoyant force combined with dimensional analysis provides two different ways to derive the Grashof number. […]

What are the types of simulation models?
What are the types of simulation models? Simulation models can be generally classified into one of three major types, namely, continuous event simulation, discrete event simulation, and Monte Carlo simulation or Monte Carlo methods (MCM). What is model in simulation and modeling? In the computer application of modeling and simulation a computer is used to […]
Why is throttling valve not replaced by an isentropic turbine in the ideal Vapour compression refrigeration cycle?
Why is throttling valve not replaced by an isentropic turbine in the ideal Vapour compression refrigeration cycle? Why is the throttling value not replaced by an isentropic turbine in the ideal vapour compression refrigeration cycle? Because the feed is a liquid and the effluent is fairly low quality, the average specific volume of the working […]
