Problem 5 A tank with square bottom, 45 cm on a side rests on a horizontal surface with coefficient of static friction of 0.08 and coefficient of kinetic friction of 0.04. An orifice, 50 mm in diameter is located 0.3 m above the bottom. Initially the orifice (C=0.60, C₁=0.98) is closed using a cork. Water stands 1.8 m above the bottom. (a) When the cork pops out, determine if the tank moves or not; (b) What is the depth of water such that the tank will start to move?

I need help on this question: According to the question: a) If the pipe connected to the pump inlet has a diameter of 24 mm with length (LCP) of 5 m and Darcy friction factor of 0.03, what would be the actual head rise across the pump for a case where the pump outlet pressure is 200 kPa? The difference in height between pump inlet and outlet is 0.25 m, the tank exit is sharp-edged, and the water level in the tank to the tank exit pipe (HWL) is 2 m. Also, consider that the flow velocity inside the tank is negligible. The value of the actual head rise across the pump is = ? b) What would be the pump motor power if the efficiency is 60%? The value of the pump motor power is = ?

Engineering a highway curve. If a car goes through a curve toofast, the car tends to slide out of the curve. For a banked curve withfriction, a frictional force acts on a fast car to oppose the tendencyto slide out of the curve; the force is directed down the bank (in thedirection water would drain). Consider a circular curve of radiusR =200 m and bank angle u, where the coefficient of static frictionbetween tires and pavement is ms. A car (without negative lift) isdriven around the curve . (a) Find an expressionfor the car speed vmax that puts the car on the verge of slidingout. (b) On the same graph, plot vmax versus angle u for the range 0to 50, first for ms =0.60 (dry pavement) and then forms =0.050 (wet or icy pavement). In kilometers per hour, evaluatevmax for a bank angle of u =10 and for (c) ms 0.60 and (d) ms 0.050. (Now you can see why accidents occur in highway curveswhen icy conditions are not obvious to drivers, who tend to drive atnormal speeds.)
