A mine airway having cross-section of 2.2 m × 2.2 m and length 500 m contains a bend. Given that the airway friction factor is 0.01 Ns2m-4, shock loss factor for the bend is 0.07 and density of air is 1.2 kg/m3, the equivalent length of the airway in m is
A mine airway 2m wide, 2.5m high and 500m long. The airway passes a quantity of 8m3 per second. Calculate its pressure loss? Assume k = 0.0098 NS2m-4
Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. What inference can be drawn from the above?
Which one of the following is true with regard to a CPU having a single interrupt request line and single interrupt grant line? i) Neither vectored nor multiple interrupting devices is possible. ii) Vectored interrupts is not possible but multiple interrupting devices is possible. iii) Vectored interrupts is possible and multiple interrupting devices is not possible. iv) Both vectored and multiple interrupting devices are possible.
The followings are definitive airway devices
