If a plus sight of 12.03 ft is taken on BM A, elevation 312.547 ft, and a minus sight of 5.43 ft is read on point X, calculate t

DochEvi [55]

Answer:

Therefore, height of instrument is 324.577 ft

Therefore, elevation of point x is 330 m

Explanation:

Given that

Plus sight on BM = 12.03 ft

Minus sight is = 5.43 ft

Elevation = 312.547 ft

Height of instrument is H.I

H.I = elevation on bench mark + plus sight

= 312.547 + 12.03 = 324.577 ft

Therefore, height of instrument is 324.577 ft

Elevation at point x is = H.I - minus sight

= 324.577 - (- 5.43)

= 330.00 m

Therefore, elevation of point x is 330 m

An insulated rigid tank is divided into two compartments of different volumes. Initially, each compartment contains the same ide

storchak [24]

Answer:

Explanation:

Given that

Mass of 1 = $m_1$

Mass of 2 = $m_2$

Temperature in 1 = $T_1$

Temperature in 2 = $T_2$

Pressure remains i the group apartment

The closed system and energy balance is

$E_{in}-E_{out}=\Delta E_{system}$

The kinetic energy and potential energy are negligible

since it is insulated tank ,there wont be eat transfer from the system

And there is no work involved

$\Delta U = 0$

Let the final temperature be final temperature

$m_1+c_v(T_3-T_1)+m_2c_v(T_3+T_2)=0\\\\m_1+c_v(T_3-T_1)=m_2c_v(T_2-T_3)---(i)$

Using mass balance

$m_3+m_2+m_1$

from eqn i

$m_1+c_v(T_3-T_1)=m_2c_v(T_2-T_3)m_1T_3-m_1T_1=m_2T_2-m_2T_3\\\\m_1T_3+m_2T_3=m_2T_2+m_1T_1\\\\(m_1+m_2)T_3=m_1T_1+m_2T_2\\\\(m_1)T_3=m_1T_1+m_2T_2\\\\T_3=\frac{m_1T_1_m_2T_2}{m_3}$

Therefore the final temperature can be express as

$\large \boxed {T_3=\frac{m_1}{m_3} T_1+\frac{m_2}{m_3}T_2 }$
