What is trapezoidal channel? Trapezoidal Channel is an open channel with a trapezoidal cross section where both sides have the same slope. The flow routing through a Channel Connection is described in Analysis of Connections. Parameters to specify: Length, Slope, Manning’s n, Diameter/Base Width, Height, Side Slope, see Connections. How do you determine the top […]
Why did the Industrial Revolution start in Great Britain in the 1750s?
Why did the Industrial Revolution start in Great Britain in the 1750s? The first Industrial Revolution began in Great Britain after 1750. By increasing food production, the British population could be fed at lower prices with less effort than ever before. The surplus of food meant that British families could use the money they saved […]
How do you find the reverse saturation current of a diode?
How do you find the reverse saturation current of a diode? Hint: We know that the current that flows in reverse bias PN junction diode is called reverse saturation current. From the diode current equation I=Is(eVηVT−1) the current should decrease as the temperature is increased but the opposite happens. What is reverse saturation current in […]
What is a ground fault protection device?
What is a ground fault protection device? A ground-fault circuit-interrupter (GFCI) is an electrical device, either a receptacle or circuit breaker, which is designed to protect people from electric shock. Even if a system is properly grounded, minor faults in a circuit can cause a dangerous shock to a person using an appliance or power […]
Which of the following is not an alloy?
Which of the following is not an alloy? Which of the following is not an alloy? Notes: • Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (such as aluminium, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus […]
Is it better to push or pull a cart?
Is it better to push or pull a cart? Avoid pulling when possible. Pushing generally takes less effort than pulling because your body weight is used to assist the exertion. Also, pulling a load often causes carts to run into the shins or ankles. What is the easiest golf cart to push? Bag Boy Nitron […]
Is a knife a lever or wedge?
Does the Laplace transform exist for all functions?
Does the Laplace transform exist for all functions? Re: Does Laplace exist for every function? As long as the function is defined for t>0 and it is piecewise continuous, then in theory, the Laplace Transform can be found. What is the Laplace transform of sin at? Let L{f} denote the Laplace transform of a real […]
