An open belt drive connects two pulleys 1.2 and 0.5m diameter on parallel shafts 3.6m apart. The belt has a mass of 0.9kg/m length and maximum tension in it is not to exeed 2kn. The 1.2m pulley which is the driver runs at 200rev/min. Due to belt slip on one of the pulleys the velocity of the driven shaft is only 450rev/min. Calculate the torque on each of the two shafts,the power transmitted and the power lost in friction. U=0.3 what is the efficiency of the drive.
Water enters a 2 meter diameter pipe at a temperature of 23 deg C. The water leaves the pipe at a temperature of 97 deg C The laminar flow rate is such that the Reynolds number is 800. What is the mass flow rate?

Calculating the mechanical properties of unidirectionally reinforced composites
Complete the sketch of the obtuse triangle. It must have an area of 1.75 in.2. Prove the geometry by dimensioning the sketch and showing the area calculation. Show only those dimensions needed for the area calculation. Note: each grid unit = .25 i..
Remember that velocity is a vector quantity so find the magnitude of the average velocity and the angle of average velocity from the horizon
