Using the data given below, calculate the drop in the temperature of molten aluminum as it flows in a 15 cm long round channel o

f 2 cm diameter in a water-cooled die and what will be the temperature drop if the metal were to flow through a 15 cm long channel having a square cross-section (side = 2 cm) in an identical mold? Assume that Al enters the channel at 800 C. The average flow velocity is 4 cm/s. Given: density of Al=2.2 g/cm3, specific heat of Al=0.28 cal/g.K, mold-metal interface heat transfer coefficient=0.01 cal/cm2.s.K, and the die temperature=27 C (assumed constant).

Answer:

c) absolute zero

Explanation:

The fourth principle of thermodynamics posed by the Romanian economist Nicholas Georgescu-Roegen, explains the presence of absolute zero is said that at this temperature the internal molecular movement becomes zero making the internal energy (U) zero, absolute zero is equivalent to -273.15C or 0Kelvin

just olya [345]

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.
