Answer:
It serves as a guarantee that the contractor who wins the bid will honor the terms of the bid after the contract is signed.
Explanation:
A bid bond is a type of construction bond that protects the obligee in a construction bidding process.
A bid bond typically involves three parties:
The obligee; the owner or developer of the construction project under bid. The principal; the bidder or proposed contractor.
The surety; the agency that issues the bid bond to the principal example insurance company or bank.
A bid bond generally serves as a guarantee that the contractor who wins the bid will honor the terms of the bid after the contract is signed.
Based on the average velocity at section 2, and the absolute pressures at both sectors, the average speed at section 1 is 2.226 m/s.
<h3>What is the average speed at section 1?</h3>
Density at P₁:
= (40 + 100) / (0.287 x (40 + 273))
= 1.5585 kg/m³
Density at P₂:
= (10 + 100) / (0.287 x (40 + 273))
= 1.2245 kg/m³
The average speed at section 1 is:
= (Density at P₂ x d² x 25.5) / (Density at P₁ x 9d²)
= 2.226 m/s

Answer:
Explanation:
The rank of the magnitude of the diffusion coefficient from greatest to least is as follows:
C in Fe at 900°C > Cr in Fe at 900°C > Cr in Fe at 600°C
Reason
C in Fe is an interstitial impurity while Cr in Fe is a substutional impurity.Therefore interstitial impurity occurs in C in Fe systems,while substutitional diffusion occurs in Cr in Fe system.Interstitial is much faster than substitutional diffusion hence the order
Also with increasing temperature magnitude of diffusion coefficient increases,due to the relation.
D = D₀exp(-Qd/RT)
Where D₀=Temperature independent per exponential
Qd= The activation energy for diffusion
R= Universal gas constant
T=absolute temperature
