a pump takes water from the bottom of a large tank where the pressure is 50 psi and delivers it through a hose to a nozzle that

is 50ft above the bottom of the tank at a rate of 100 ibm/s. the water exits the nozzle into the atmosphere at a velocity of 70ft/s.if a 10hp motor is required to drive the pump which is 75% efficient, find:the friction loss in the pump

Answer:

The friction loss in the pump is 442.12 lb*ft/slug

Explanation:

the efficiency is

n=\frac{W_{shaft}-W_{loss}}{W_{shaft} } =0.75\\W_{shaft}=\frac{pump-power}{flow-rate}

pump power = 10 hp = 5500 lb*ft*s⁻¹

flow rate = 100 lbm/s = 3.11 slug*s⁻¹

W_{shaft} =\frac{5500}{3.11} =1768.48 lbft/slug

Clearing Wloss in equation of efficiency

0.75=\frac{1768.48-W_{loss} }{1768.48} \\W_{loss} =442.12lbft/slug

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
