Calculate the volume of a hydraulic accumulator capable of delivering 5 liters of oil between 180 and 80 bar, using as a preload

Vinil7 [7]

Answer:

1) $V_o = 10 liters$

2) $V_o = 12.26 liters$

Explanation:

For isothermal process n =1

$V_o =\frac{\Delta V}{(\frac{p_o}{p_1})^{1/n} -(\frac{p_o}{p_2})^{1/n}}$

$V_o = \frac{5}{[\frac{72}{80}]^{1/1} -[\frac{72}{180}]^{1/1}}$

$V_o = 10 liters$

calculate pressure ratio to determine correction factor

$\frac{p_2}{p_1} =\frac{180}{80} = 2.25$

correction factor for calculate dpressure ration for isothermal process is

c1 = 1.03

$actual \ volume = c1\times 10 = 10.3 liters$

b) for adiabatic process

n =1.4

volume of hydraulic accumulator is given as

$V_o =\frac{\Delta V}{[\frac{p_o}{p_1}]^{1/n} -[\frac{p_o}{p_2}]^{1/n}}$

$V_o = \frac{5}{[\frac{72}{80}]^{1/1.4} -[\frac{72}{180}]^{1/1.4}}$

$V_o = 12.26 liters$

calculate pressure ratio to determine correction factor

$\frac{p_2}{p_1} =\frac{180}{80} = 2.25$

correction factor for calculate dpressure ration for isothermal process is

c1 = 1.15

$actual \volume = c1\times 10 = 11.5 liters$

Conduction is thermal energy transfer by:_______.

adell [148]

Answer:

a. molecular interactions.

Explanation:

Conduction is thermal energy transfer by molecular interactions. Therefore, conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Some examples of conductors include metal, steel, aluminum, copper, graphite, etc.

Hence, conduction is thermal energy transfer as a result of the movement of electrons and collision between the molecules of an object.

A circular copper bar with diameter d 5 3 in. is subjected to torques T 5 30 kip-in. at its ends. Find the maximum shear, tensil

Ivenika [448]

Answer:

Maximum shear stress= 5.66 ksi

Maximum tensile stress= 5.66 ksi

Maximum compressive stress=-5.66 ksi

Maximum shear strain=0.000943

Maximum tensile strain= 0.0004715

Maximum compressive strain= -0.0004715

Explanation:

For acircular bar, the maximum shear stress will be given by

$\frac {16T}{\pi d^{3}}$ where d is the diameter and T is torque.

By substituting 30 kip-in for torque and 3 in for d then

Maximum shear stress= $\frac {16*30}{\pi *3^{3}}\approx 5.66 ksi$

Also, the maximum tensile and compressive stresses will be 5.66 ksi and -5.66 ksi respectively.

The maximum shear strain will be given by stress divided by modulus of elasticity, in this case 6000 G

Maximum shear strain will be $\frac {5.66}{6000}\approx 0.000943$

The maximum tensile strain will be the above divided by 2 whereas the maximum compressive strain will be negative of tensile strain hence $\frac {0.000943}{2}=0.0004715$

Maximum compressive strain will be $\frac {-0.000943}{2}=-0.0004715$
