3. Two coaxial cylinders 250 mr high have a liquid in between them, the outer cylinder had internal diameter 100 mm and the internal cylinder has external diameter 97.5 mm. Find the viscosity of liquid which produces a torque of 1 Nm upon the inner cylinder when outer one rotates at 90 rpm.

Please state any assumptions required to solve problem

In a pump test the suction pressure at the pump inlet is -28.00 kPa below atmospheric pressure. The discharge pressure at a point 960 mm above the inlet is 525 kPa. Hydraulic steel tubing is used for both the suction (inlet) and discharge (outlet) lines with 80 mm OD × 2.8 mm wall. Required If the volume flow rate of water is 88 L/min, calculate the power delivered by the pump to the water in kW, to the nearest 1000th. Discharge pipe Suction pipe Flow Pump |||+

Please explain all parts

A compound shaft consists of a titanium alloy [G= 6,200 ksi] tube (1) and a solid stainless steel [G= 11,500 ksi] shaft (2). Tube (1) has a length of L₁ = 38 in., an outside diameter of D₁ = 2.25 in., and a wall thickness of t₁ = 0.130 in. Shaft (2) has a length of L₂ = 66 in. and a diameter of d₂ = 1.35 in. If an external torque of Tg = 660 lb-ft acts at pulley B in the direction shown, calculate the torque Terequired at pulley C so that the rotation angle of pulley C relative to A is zero.
