Answer:
The correct option is;
To be able to switch between different heads quickly and easily
Explanation:
A screwdriver is a tool or device that has a grip handle which surrounds an extension shaft that has a forged tip that fits into the complementary groove on a screw head such that by turning the handle while the forged head of the screwdriver sits in a screw head, the screw is turned
A convertible screw driver is built with the capability to easily change the tip or other attributes of the screwdriver quickly.
Answer:
The curve length (<em>L</em>) will be = 1218 ft
The elevations and stations for PVC and PVI
a. station of PVC = 103 + 91.00
b. station of PVI = 116 + 09.00
c. elevation of PVC = 432.18ft
d. elevation of PVI = 426.09ft
Explanation:
First calculate for the length (<em>L</em>)
To calculate the length, use the formula of "elevation at any point".
where, elevation at any point = 424.5.
and ∴ PVC Elevation = (420 + 0.01L)
Then, calculate for Station of PVC and PVI and elevation of PVC and PVI
Answer:
Option C
Explanation:
The image given in the question represents an overflow tank
Since a water pump has rotor and blades (which is not visible in the given image), hence, this image is not of water pump.
The surge tank has a different structure as compared to that of overflow tank
Radiator looks like a metallic structure with parallel blades.
Hence, option C is correct
Answer:
See image attached.
Explanation:
This device features priority encoding of the inputs
to ensure that only the highest order data line is en-
coded. Nine input lines are encoded to a four line
BCD output. The implied decimal zero condition re-
quires no input condition as zero is encoded when
all nine datalinesare athigh logic level. Alldata input
and outputs are active at the low logic level. All in-
puts are equipped with protection circuits against
static discharge and transient excess voltage.
Answer:
Explanation:
given data
loading rate = 8.00 m/h
filtration rate = 7.70 m/h
dimensions = 10 m × 8 m
filter cycle duration = 52 h
time = 20 min
to find out
flow rate and volume of water is used for back washing plus rinsing the filter
solution
we consider here production efficiency is 96%
so here flow rate will be
flow rate = area × rate of filtration
flow rate = 10 × 8 × 7.7
flow rate = 616 m³/h
and
we know back washing generally 3 to 5 % of total volume of water per cycle so
volume of water is = 616 × 52
volume of water is 32032 m³
and
volume of water of back washing is = 4% of 32032
volume of water of back washing is 1281.2 m³
