The melting temperature of pure titanium = 1668°C, its density = 4.5 g/cm^3, specific heat = 0.544 J/gºC, and heat of fusion = 4
nataly862011 [7]

Answer:

A) 1384.6 J/g

b)110.768 MJ

Explanation:

Given data:

T_{melting} = 1668 degree C

density of titanium =  4.5 g/cm^3

specific heat = 0.544 J/g degree C

heat of fusion = 419 J/g

Pouring temperature for titanium = 1800 degree  C

Initial temperature  =  25 degree C

a) eneegy for heating unit mass is given as

E = C(T_{melting} - T_{initial}) + L + C(T_{pouring} - T_{melting})

   = 0.544(1668-25) + 419 + 0.544(1800-1668)

   = 1384.6 J/g

b) Total energy to heat 80 kg metal

we know  for one unit  1384.6 J/g energy is required

therefore for 80 kg , energy required is

E = (80\times 1000) 1384.6

   = 110768000 J

   = 110.768 \times 10^6 J

Volgvan

Answer:

25120 N

Explanation:

The external load acting on each bolted joint

= P x A / N

= (8 x 10⁶) (31.4 x 10³ x 10⁻⁶) / 10

= 25120 N

How much will it cost to train the entire company to use a recycling program if the training includes paper handouts? (Remember,
bezimeni [28]

Answer:

With the current budget of $1,000, it is possible to train the company and buy 3 recycling carts given that recycling pickup within the area is free

Explanation:

The office waste management budget that is not being spent = $1,000

The given expense parameters are;

The training cost per hour per employee = $12.00

The number of people in the entire company = 45

The cost of preparing the training material per hour = $20.00

The number of people to create the training material = 3 people

The time it will take each person in creating the training material = 3 hours

The cost of recycling cart = $80.00 per cart

The cost of paper handouts per employee = $0.05

The cost of materials include;

The total cost for the training = $12.00 × 45 = $540

The cost for the handout = $0.05 × 45 = $2.25

The cost of preparing the materials = $20.00 × 3 × 3 = $180.00

The total costs of the training = $540 + $4 + $180.00 = $724

The amount available to buy cart = $1,000 - $724 = $276

Therefore;

The amount available to buy cart = $276

The number of carts that can be bought = 276/80 = 3.45 carts

Therefore, we round down to get;

The number of carts that can be bought = 3 carts
