Wаter аt а vоlume flоw rate оf [x] m3/s enters the nozzle-bend shown that turns the flow 120 degrees. The inflow area is 0.1 m2 and the outflow area is 0.04 m2. The flow enters with a gage pressure of [y] kPa and exits to the atmosphere. Use the density of water as 998 kg/m3 . Assume turbulent flow having a correction factor of 1.03. a. Sketch the nozzle bend, show the coordinate system and control volume being used to find the reaction force required to hold the nozzle-bend in place. Draw and label the reaction force in the correct location and in the assumed direction. b. Determine the reaction force in the x direction required to hold the nozzle in place. For full credit, the sign of the force needs to be consistent with the direction label in your sketch. In the box below, enter the reaction force in the x-direction without units. Include three digits in your answer and give the numerical answer in kN.
Hоckey Heаven Inc. is cоnsidering purchаsing а new arena being built in dоwntown Edmonton, but management wants to know the company’s current cost of capital before proceeding. From the recently completed year-end financials, the following is the BOOK VALUE of the company’s capital structure: Bonds ($1,000 par each) $12,000,000 Preferred shares (100,000 shares) 2,500,000 Common shares (1,000,000 shares) 8,000,000 Retained earnings 3,000,000 $25,500,000 The long term debt has 15 years to maturity, an 11% coupon (paid annually) and the current bond price is $1,076.06. A new debt issue would have a flotation cost of 2.0% of the funds raised. The preferred shares are trading at $30/share and have a 9% dividend. A new issue would require a flotation cost of 4%. The company has enjoyed steady growth for the last 4 years, with dividends growing from $0.80 to $1.01 per share (D0 - just paid). The same rate of growth will continue, going forward. The shares are currently trading at $14.50 per share. Flotation costs for new common shares would be 8%. Internally generated funds will be sufficient to support future projects. The tax rate is 42%.
