A rigid canister with a radius of 5 in and a height of 10 in is filled with air. The initial pressure and temperature of air in

Elza [17]

Answer:1.458 Btu

Explanation:

Given

radius of canister $\left ( r\right )=5in$

Height of canister $\left ( h\right )=10 in.$

Initial pressure $\left ( P_i\right )=14.7 Psi$

Initia ltemprature $\left ( T_i\right )=70^{\circ}F$

Final pressure $\left ( P_f\right )=30Psi$

as canister is rigid therefore change in volume is zero

therefore

$\frac{P_i}{T_i}$ = $\frac{P_f}{T_f}$

$\frac{14.7}{70}$ = $\frac{30}{T_f}$

$T_f=142.85^{\circ}F$

volume of canister= $\pi \times r^{2}\times h$

= $\pi \times 5^{2}\times 10=250\pi$

volume of canister=12872,038.8 $mm^3$

now calculating mass of air

PV=mRT

substituting values

$\left ( 14.7Psi\right )\left ( 12872,038.8 mm^3\right )=m\left ( 0.287\right )\left ( 70^{\circ}F\right )$

m=21.0192 gm

Therefore heat transferred = $mc_p\left ( T_f-T_i\right )$

= $21.0192\times 10^{-3}\times \left ( 142.857-70\right )$

=1539.052J=1.458Btu

A tank containing diesel fuel(SG = 0.8) is open to the atmosphere at the top. A U-tube manometer is connected to the bottom of t

stepan [7]

Answer:

h= 37.9 m

Explanation:

Given that

SG = 0.8 for fuel so density of fluid will be 800 kg/m³.

We know that SG = 13.6 For Hg so density will be 13600 kg/m³.

Now by balancing the pressure

$\rho_d\times g\times h +\rho_d\times g\times 1.2 =\rho_{hg}\times g\times 2.3$

$800\times 9.81\times h+ 800\times 9.81\times 1.2 =13600\times 9.81\times 2.3$

$800\times 9.81\times h =13600\times 9.81\times 2.3-800\times 9.81\times 1.2$

$h=\dfrac{297439.2}{800\times 9.81}$

h= 37.9 m

John wants to construct a device using quartz crystal, Which device can he construct?

tatiyna

Answer: Option D, piezoelectric pressure guage

Explanation: Quartz crystal possess a very useful quality in science as they can generate small charges when pressure is applied to them or when they are hit. This property can be harnessed to construct a piezoelectric pressure gauge which would be used to measure and indicate changes in pressure, the quartz crystal releases little voltage each time there is an applied pressure . This device would be able to sense changes in pressure as there would voltage proportional to the applied pressure.
