Estimate force and power required to overcome skin friction
A supertanker is 360 m long and has a beam width of 70 m and a draft of 25 m. Estimate the force and power required to overcome skin friction drag at a cruising speed of 13 kt in sewater at 10 degrees centigrate?

A researcher is interested in estimating the mean length of walleye in a lake with a 95% confidence interval. Assuming the standard deviation of lengths is inches, estimate the sample size required so that margin of error does not exceed 3 inches.
Saturated mixture of water at 1500kPa is throttled to 100kPa and 150 degree C in a steam line. Calculate the temperature and quality of the water at the inlet.
A spring having an unstreched length of 2ft has one end attached to a 10lb ball. Determine the angle of the spring when the ball has a speed of 6 ft/s tangent to horizontal cicular path. k=20lbs.
Assume the population standard deviation is 2.1 pounds. b. Physician thinks that the margin of error is too large. Estimate the sample size required to estimate the mean birth weight within 0.3 pounds with a 98% confidence interval.
Estimate the force and power required to overcome skin friction drag at a cruising speed of 13 kt in sewater at 10 degrees centigrate?
5 Lbm of Refrigerant 22 (R-22) is contained in a piston cylinder device. The R-22, initially at a pressure of 30 psia and a volume of 4 ft^3, is heated at constant pressure until the temperature is 70 degrees F.
What would be the maximum electrical power output (called peak rated power) of the PV module at standard test conditions?
A sample has a mean of 120 and a standard deviation of 20.0. Find the value x that corresponds to each of these standard scores. Use the following formula:
A steam power plant has a high pressure of 3 MPa, and it maintains 60°C in the condenser. A condensing turbine is used, but the quality should not be lower than 90% at any state in the turbine.
