1.What is the shear rate in the water between a sliding and standing plate, if V = 10 ft/s is the moving plate velocity and 0.1 in. is the distance between the plates? How much force is acting upon each in.^2 of either of the plates by the water? Will rate LIFESAVER if show work.

2.Create a primary function that uses a function handle with a nested function to compute the minimum of the function 20x2-200x+12 over the range 0<=x<=10.

## Estimate the minimum absolute pressureWhen a fluid flows through a sharp bend, low pressures may developin localized regions of the bend. Estimate the minimumabsolute pressure (in psi) that can develop without causingcavitation if the fluid is water at 160 oF. |

## Calculate the velocity of air at the entry in ft per secondA compressor pressurizes air from 1 atm to 2.38 atm at steady state. At the entry the air's temperature is 70F, whereas at the exit it has quadrupled (in degrees F). At the entry the air's volumetric flow rate is 17 ft3/s |

## What is the minimum grade a student must get in orderThe mean grade on a final examination was 72, and the standard deviation was 9. The top 10% of the students are to receive A's. What is the minimum grade a student must get in order to receive an A |

## Calculate the steady-state pollutant concentration in lakeConditions in the sewage pipe are Qs= 0.5 m^3/s, and Cs= 100mg/L. The pollutant is destroyed in the lake with a first-order rate constant of 0.2/d. The flow rate out of the lake is 5.0 m^3/s. |

## Find wall friction head loss and the friction force on ductWater at 60 degrees Fahreneit flows at 3 cfs through a 150-ft-long duct of 6 in X 9 in cross section. The pressure at the inlet end is 15 psig, and at the outlet, 20 ft higher than the inlet, it is 4 psig. |

## Principal stresses and calculate the max shear stressAt a section in a beam the tensile stress due to bending is 70 N/mm 2 and there is a shear stress of 25 N/mm 2 . Determine from first principles, the magnitude and direction of the principal stresses and calculate the max shear stress. |

## Determine the landing speed of the airplane if it travelsA 32000 lb airplane lands on an aircraft carrier and is caught by an arresting cable. The cable is inextensible and is paid out at A and B from mechanisms located below deck and consisting of pistons moving in long oil-filled cylinders. |
