What is the balanced equation for C3H8? C3H8 + O2 = CO2 + H2O – Chemical Equation Balancer. What is produced during the combustion of propane C3H8? Propane (C3H8) is a hydrocarbon that belongs to the homologous series alkanes. Thus, propane will undergo combustion to form 3 molecules of carbon dioxide and 4 molecules of […]

How does an ohmmeter measure resistance? Resistance is measured with the circuit’s power turned off. The ohmmeter sends its own current through the unknown resistance and then measures that current to provide a resistance value readout. How would you use an ohmmeter to check the status of a light bulb? Steps for Testing the Bulb […]

What is the characteristics of transfer function? The properties of transfer function are given below: The ratio of Laplace transform of output to Laplace transform of input assuming all initial conditions to be zero. The transfer function of a system does not depend on the inputs to the system. The system poles and zeros can […]

Is percentile rank a percentage? Percentile ranks are commonly used to clarify the interpretation of scores on standardized tests. For the test theory, the percentile rank of a raw score is interpreted as the percentage of examinees in the norm group who scored below the score of interest. What is the percentile rank of a […]

What is the effect of grain size on the strength of materials at room temperature? Smaller grains have greater ratios of surface area to volume, which means a greater ratio of grain boundary to dislocations. The more grain boundaries that exist, the higher the strength becomes. The following example illustrates this principle. How does grain […]

How does a geothermal heat pump work? Geothermal heat pumps work by tapping into the renewable solar energy stored in the ground to provide savings of up to 72% on heating and cooling costs. Although it operates similarly to a standard heat pump, a geothermal heat pump exchanges heat with the earth instead of the […]

What is difference between orifice meter and Venturi meter? A Venturi meter is designed to have three parts; the converging section, the throat and the diverging section. Pressure taps are provided before the converging part and at the throat in order to measure the drop in pressure. An orifice meter is consists a thin plate […]

What are the method of measuring temperature? One of the most common devices for measuring temperature is the glass thermometer. This consists of a glass tube filled with mercury or some other liquid, which acts as the working fluid. Temperature increase causes the fluid to expand, so the temperature can be determined by measuring the […]

What happens to the speed of the ball as it rolls down the ramp? What happens to the speed of the ball as it rolls down the ramp? As the ball rolls down the ramp, the speed increases. This can be inferred because it is known that the ball takes the same amount of time […]

What is the purpose of systems engineering? The systems engineer usually plays the key role in leading the development of the concept of operations (ConOps) and resulting system architecture, defining boundaries, defining and allocating requirements, evaluating design tradeoffs, balancing technical risk between systems, defining and assessing interfaces, and … What is functional analysis system engineering?
