Answer Explanation :

ADVANTAGES OF ISOTHERMAL PROCESS

  • EASE OF MAINTENANCE: there is absence of direct contact between the combustible gas mixture and all moving part in this process
  • LESS NOISE : These engines does not have valves so it is very simple in construction and produce less noise
  • BETTER PERFORMANCE : these engine have better performance than other engines
  • LOW TEMPERATURE : these engine can work on low temperature which is also an advantage

DISADVANTAGES OF ISOTHERMAL PROCESS :

  • GREATER VOLUME AND GREATER WEIGHT: These engine require large volume and large weight
  • SLOWER START: In this process the engine have very slower start which is a disadvantage
  • HIGHER ECONOMIC COST : In this process we need more money this is also an disadvantage

Scorpion4ik [409]

Answer:

The settlement that is expected is 1.043 meters.

Explanation:

Since the pre-consolidation stress of the layer is equal to the effective stress hence we conclude that the soil is normally consolidated soil

The settlement due to increase in the effective stress of a normally consolidated soil mass is given by the formula

\Delta H=\frac{H_oC_c}{1+e_o}log(\frac{\bar{\sigma_o}+\Delta \bar{\sigma }}{\bar{\sigma_o}})

where

'H' is the initial depth of the layer

C_c is the Compression index

e_o is the inital void ratio

\bar{\sigma_o} is the initial effective stress at the depth

\Delta \bar{\sigma_o} is the change in the effective stress at the given depth

Applying the given values we get

\Delta H=\frac{8\times 0.3}{1+0.87}log(\frac{154+28}{154})=1.04

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a
muminat

Answer:

a. true

Explanation:

Firstly, we need to understand what takes places during the compression process in a quasi-equilibrium process. A quasi-equilibrium process is a process in during which the system remains very close to a state of equilibrium at all times.  When a compression process is quasi-equilibrium, the work done during the compression is returned to the surroundings during expansion, no exchange of heat, and then the system and the surroundings return to their initial states. Thus a reversible process.

While for a non-quasi equilibrium process, it takes more work to move the piston against this high-pressure region.
