Answer:
B. with each component having an individual address
Explanation:
A data bus is a system within a computing system, that consists of a set of wires or connectors, that provides transportation for data. A data bus can transfer data and information through a computing system, or between two or more computing systems. Each component in the computer has its own unique address by which data or information is sent to it, to or fro the central processing unit, and the data or information travelling through the data bus, which serves as the highway, reaches each component using this address. This is analogous to the postal service system of moving letters and packages, through a series of networks that locates the address of the receiver.
Answer:
ratio = 412
speed of wheel = 13.63
Explanation:
given data
head h = 91.5 m
discharge Q = 0.04 m³/s
wheel rotates N = 720 rpm
velocity coefficient Cv = 0.98
efficiency of the wheel η = 80 %
ratio of bucket speed to jet speed = 0.46
to find out
wheel to jet diameter ratio and power specific speed of the wheel
solution
we know that discharge = area × velocity .............1
here velocity = Cv√(2gh)
velocity = 0.98√(2×9.81×91.5) = 41.52 m/s
and area =
so from equation 1
0.04 = × 41.52
d = 0.00123 m = 1.23 mm
we know bucket speed to jet speed = 0.46
so bucket speed u = 0.46 v
bucket speed u = 0.46 × 41.52 = 19.1 m/s
and bucket speed =
so 19.1 =
so D = 0.506 m = 506.62 mm
so ratio is
ratio = 412
and
we know efficiency =
0.80 × ρQgh = output power
power output = 0.80 ×1000×0.04×9.81×91.5
power output P = 28.72 kW
so
speed of wheel is
speed of wheel =
speed of wheel =
speed of wheel = 13.63
