A model of a Francis turbine is built to a scale of one fifth of full size and when tested it developed a power output of 3 kW under a head of 1.8 m of wate

A model of a Francis turbine is built to a scale of one fifth of full size and when tested it developed a power output of $3 \mathrm{~kW}$ under a head of $1.8 \mathrm{~m}$ of water, at a rotational speed of $360 \mathrm{rev} / \mathrm{min}$ and a flow rate of $0.215 \mathrm{~m}^3 / \mathrm{s}$.Estimate the speed, flow rate, and power of the full-scale turbine when working under dynamically similar conditions with a head of $60 \mathrm{~m}$ of water. By making...

15. A four stroke oil engine developing 75 kW at 300 r.p.m is to have the total fluctuation of speed limited to 5%. Two identical flywheels are to be designed. The workdone during the power stroke is found to be 1.3 times the average workdone during the whole cycle. The turning moment diagram can be approximated as a triangle during the power stroke. Assume that the hoop stress in the flywheel and the bending stress in the arms should not...

1. IDM purchases one model of computer at a wholesale cost of $300 per unit and resells it to end consumers. The annual demand for the company’s product is 600,000 units. Ordering costs are $1,200 per order and carrying costs are $75 per computer, including $30 in the opportunity cost of holding inventory. It currently takes 2 weeks to supply an order to the store. assume that demand can vary during the 2-week purchase-order lead time. The following table shows...

Builders need to predict the final selling price of a home. For one model using size (x), in square feet, to predict price (y), in U.S. dollars, a slope of 77 was found. Interpret this slope in context. a. If a house costs one more dollar, it is predicted to increase in size by 77 square feet, on average. b. If a house increases in size by one square foot, it is predicted to cost $77 more, on average. c....
