1.laminar flow of a real fluid down a cylindrical pipe of constant radius R. Poiseuille showed that the velocity profile was parabolic and given by u(r)=c(R^2-r^2), where r is the radial coordinate and c is a dimensional constant. what is the mean momentum flow rate down the pipe?
2.Provided that the amplitude is sufficiently great, the human ear can respond to longitudinal waves over a range of frequencies from about 20 Hz to about 20000Hz. Compute the wavelength corresponding to these frequencies a.) for waves in air ( v= 344 m/s); b.) for waves in water ( v=1480 m/s).
A Rankine cycle has a boiler pressure of 2500 psi and a condenser pressure of 1psi. The temperature at the inlet of the turbine is 800F. The turbine has an isentropic efficiency of 90 percent and the pump operates isentropically.
What is the largest circle that can be inscribed within a polygon with corner coordinates (600,800), (900, 300), (500, 100), and (100, 40) Find the radius of the largest circle and show how you found it from these coordinates.
A sample of mortar fills a900 ml beaker. The mortar and beaker combined weighs 3 lb and theempty beaker weighs 2 oz. What is the weight density of this mortar sample
A meat packing plant manager is trying to decide between twodifferent methods for cooling cooked hams. the spray methodinvolves spraying water over the hams until the ham temperature isreduced to 30 degrees Celcius. With this method approximately 80l..

Write an M-file to calculate the factorial function of N!, as defined by: N!=1 N=0 N!=N*(N-1)*(N-2)*...*3*2*1 N>0 The MATLAB code to calculate N factorial for positive value of N would be n_factorial=1
Initially the air in this tank is at 20 psia and 70 degrees F. Presuming that the ank is well insulated determine the temperature and mass in the tank when it is filled to 120 psia.
A lagoon with volume 1200 m3 has been receiving a steady flow of a conservative waste at a rate of 100 m3/day for a long enough time to assume that steady-state conditions apply. The waste entering the lagoon has a concentration of 10 mg/L. Assuming ..
A solid composite shaft is subjected to a 2MN force. Section AB is red brass (E= 120 Gpa), and section BC is AISI 1010 steel (E=200GPa). Find the normal stress in each section and the total axil deformation of the shaft.
A solid titanium is titghly inserted into a hollow section of length l/2 and constan thickness t=7.5mm , and extends from end B towards end A. determine the shear streess and angle of twist at B.
On the two lane carriageways, roadworks restrict the width of both traffic lanes, generating a bottleneck to the traffic flow. The maximum flow per lane on the unobstructed carriageway is 2100 vehicles per hour whilst on the section under repairing t..
The dissolved oxygen of sample water is 1.5 mg/L. At 25 C, the dissolved oxygen of the dilution water is 8.25 mg/L. You are told the BOD5 of the sample is 130 mg/L. You have a target final dissolved oxygen of 3.0 mg/L
