Water at 15Â°C (rho = 999.1 kg/m^3) from a garden hose fills a 1.5-L container in 2.5 s. Assume that the volume flow rate, tempe

BaLLatris [955]

Answer:

36 Lpm

Explanation:

We can calculate the volumetric flow rate with conversion factors. We have the volume and we have the time. This is a simple calculation:

$=1.5/2.5=0.6$

Which is 0.5 L/s. We must convert s to min. We know that 1 min has 60 seconds, so 23 multiply 0.6 by 60:

$=0.6\cdot{60}=36$

The volume flow rate is equal to 36 Lpm

A cylinder contains 480 cm3 of loose dry sand which weighs 820 g. Under a static load of 200 kPa the volume is reduced 1%, and t

goblinko [34]

Answer:

Explanation:

a. void ratio is provided by the formula: $e = \frac{V_{p} }{V_{s} }$

where , $V_{p}$ = volume of voids

$V_{s}$ = volume of solid grains

for loose sand, the void space = $\frac{480}{480}$

= 1

b. void ratio after static load = 0.1/(480)/ (480)

= 0.1

c. void ratio after vibration = [480- ( 0.1 * 480) ]/ 480

= 0.9

A motor is mounted on a platform that is observed to vibrate excessively at an operating speed of 6000 rpm producing a 250-N for

vichka [17]

Answer:

The amplitude of the absorbed mass can be found

for ka:

$X_{a} =0.002m=\frac{F_{0} }{K_{a} } =\frac{250}{K_{a} } =125000N/m$

now

$w^2=\frac{K_{a} }{m_{a} } \\m_{a} =\frac{K_{a} }{w^2} =\frac{125000}{[6000*2\pi /60]^2} =0.317kg$
