A pressure gage and a manometer are connected to a compressed air tank to measure its pressure. If the reading on the pressure g

age is 11 kPa, determine the distance h between the two fluid levels of the water filled manometer. Assume the density of water is 1000 kg/m3 and the atmospheric pressure is 101 kPa.Quiz 3

Answer:

h=1.122652m

Explanation:

Assuming density of air = 1.2kg/m³

the differential pressure is given by:

h^{i} =h(\frac{density of manometer}{density of flowing air}-1)\\h^{i} =h(\frac{1000}{1.2}-1)\\ h^{i}=832.33h...(1)\\\\but\\ h^{i} =\frac{change in pressure}{air density*g} \\\\h^{i} =\frac{11*10^3}{1.2*9.81}\\\\h^{i}= 934.42...(2)\\\\equating, \\\\934.42=832.33h\\\\h=1.122652m

Answer:

MRS = -2.23 (x2/x1)

Explanation:

The concept of Marginal rate of substitution(MRS) is applied here. MRS occurs when a consumer is willing to give up a good at the expense of another whilst still maintaining the same utility. The principle of partial differentiation is mostly applied in MRS Calculation.

From MRS = -(MUx/MUy)

The steps are as shown in the attachment

If you are sampling a 50Hz signal, what is the minimum sampling rate necessary to prevent aliasing?Why?
horsena [70]

Answer:

100Hz

Explanation:

The minimum sampling rate to prevent aliasing is at least double your sample frequency.

50*2 = 100Hz

This is called the Nyquist Sampling Rate if you wanna learn more about it.

lakkis [162]

Answer:

both statement is correct

Explanation:

Flywheel engine uses to reduce fluctuations.

And                                                                

FlexPlate is a metal disk that connects the output from the engine to the input of the torque converter. This will replace the flywheel

so that both statement is correct

fiasKO [112]

Answer:

-475.68kJ

Explanation:

P1=116kPa

V1=3m³

T1=420K

P2=455kPa

Formula for workdone in isothermal process=P1×V1×In(p1/p2)

Workdone=116×3×in(116/455)

Workdone=-475.68kJ

The result is negative because work is done on the system
