An oil gusher shoots crude oil 25.0 m into the air through a pipe with a 0.100-m diameter. neglecting air resistance but not the resistance of the pipe, and assuming laminar flow, calculate the gauge pressure at the entrance of the 50.0-m-long vertical pipe. take the density of the oil to be 900 kg/m3 and its viscosity to be 1.00 (n/m2 )â‹…s (or 1.00 paâ‹…s). note that you must take into account the pressure due to the 50.0-m column of oil in the pipe
