How do you calculate hydraulic conductivity from permeability? It is the soil’s hydraulic conductivity after the effect of fluid viscosity and density are removed. It is calculated as hydraulic conductivity (K) multiplied by the fluid viscosity divided by fluid density and the gravitational constant. Permeability (k) has the dimension of area (e.g., cm2). What does […]

How much thrust does it take to lift 100KG? To lift a 100KG payload you need thrust greater than Payload +vehicle weight+ fuel weight + excess thrust to accelerate. The Williams FJ33 is in the 5000-7000N thrust range, with a basic dry mass of about 150Kg. What aircraft has the best thrust-to-weight ratio? For many […]

Is it better to wire solar panels in series or parallel? The main thing to remember is that wiring in series will increase your voltage, while wiring in parallel will increase your amperage. Both of the voltage and amperage need to be considered when designing your system, especially when it comes to finding an inverter […]

How do you find the impulse response of an LTI system? The impulse response for an LTI system is the output, y ( t ) y(t) y(t), when the input is the unit impulse signal, σ ( t ) \sigma(t) σ(t). In other words, when x ( t ) = σ ( t ) , […]

What is a hydraulic power unit? What is a Hydraulic Power Unit? Hydraulic Power Units are the main driving components of hydraulic systems. Consisting mainly of a motor, a reservoir and a hydraulic pump, these units can generate a tremendous amount of power to drive most any kind of hydraulic ram. What are hydraulics powered […]

What is Murphree tray efficiency? The Murphree vapor-phase tray efficiency (ηtray) defines the fractional approach to equilibrium for a single cross-flow tray based on the vapor concentrations on the operating and equilibrium lines. 4 is constant across the tray, and the vapor concentration below the tray is uniform. How do you calculate distillation efficiency? Calculate […]

What are the metal products? Metals & Metal Products Alloys. Aluminum. Angles & Channels. Bars & Rods. Beryllium. Bismuth. Brass & Brass Alloys. Brazing Alloys. What is a sheet metal shop? Sheet Metal Shop: This may seem pretty self explanatory, but a sheet metal shop is a shop that fabricates parts out of sheet metal. […]

Which is the best algorithm for sorting? Quicksort Which is the fastest sorting algorithm in Java? Quicksort is a fast, recursive, non-stable sort algorithm which works by the divide and conquer principle. Quicksort will in the best case divide the array into almost two identical parts. It the array contains n elements then the first […]

What is cumulative in Binomial Distribution for Excel? The binomial distribution is a statistical measure that is frequently used to indicate the probability of a specific number of successes occurring from a specific number of independent trials. The Cumulative Distribution Function – Calculates the probability of there being at most x successes from n independent […]

How do you find the cross sectional area of a tube? Square this radius. In the example, 4^2 = 16 square inches. Multiply the result by pi, which is approximately 3.142 — 16 x 3.142 = 50.27 square inches. This is the pipe’s cross-sectional area. How do you calculate cross sectional area? The area of […]
