1.A venturi meter installed in a pipe with a 38.10cm diameter has a throat diameter of 21.24cm. The static gage presure upstream of the venturi is 172.4kPa. The average fluid velocity in the pipe is 7.62 m/s. The fluid flowing is water. If cavitation is just beginning at the throat of the venturi, what is most nearly the absolute vapor pressure of the water at the throat?
2.The tractor boom supports a uniform mass of 500 kg in the bucket which has a center of mass at G. Determine the force in each hydraulic cylinder AB and CD and the resultant force at pins E and F. The load is supported equally on each side of the tractor by a similar mechanism.
A solid circular shaft AC of total length L=L1+L2 is fixed against rotation at ends A and C and is loaded by a tourqe T_b at joint B. If the diameter of the two segements of the shaft are in ratio d2/d1
for this purpose replace this force by its equivalent of two forces at At Ft parallel and Fn perpendicular to the beam. Determine Ft and Fn.
A 0.02wt% C steel is to be carburized at 1200°C in 4 hrs with a point 0.6mm beneath the surface reaching 0.45wt%C. calculate the carbon content required at the surface of the steel.
Determine the settlements when a stress of 100 kPa is applied by the building over an area of 10m × 5 m on the soil surface.
on a specific westbound section of highway studies show that the speed-density relationship is u= uf [1-(k/kf)^3.5] It is known that the capacity is 4200 veh/h and the jam density is 210 veh/mi.
The traffic that makes a left turnat an intersection consists of two types of vehicles, Type A andB. A type A vehicle is twice the length of the type B. THe left turn lane can accommodate ten vehicles of type B, five oftype A.
a driver in a vehicletraveling 40 mph shifts his eyes from right to left and focuses ona child about to dart across the street. estimate the distance infeet the vehicle travels as the driver's eye shift and fixate
The crane hoists a uniformly distributed load C. the two identical motors at A an power through gearboxes operating at maximum output speed of 100 rpm.the load is lifted by winding cable onto spindles attached to the output shaft of each gear box.
The hydraulic conductivity of a coarse sand was measured in the laboratory permeameter and found to be 1.03x10^-2 cm/s at 25 degrees C. What is the intrinsic permeability
A fan is to be selected to ventilate a bathroom whose dimensions are 2 m x 3 m x 3 m. The air velocity is not to exceed 8 m/s to minimize vibration and noise.
