Write a program that lets a user enter n and that outputs n! (n factorial, meaning n*(n-1)*(n-2)*..\.\*2*1). hint: initialize a variable total to n (where n is input), and use a loop variable i that counts from total-1 down to 1. compare your output with some of these answers: 1: 1, 2: 2, 3: 6, 4: 24, 5: 120, 8: 40320.

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false

Aplate of dimensions 3 m x 3 m is placed 0.37 mm apart from a fixed plate. the plate requires a force of 2n to move at speed of 45 cm/s. evaluate the viscosity of the fluid in between the plates
