Hydraulic fluid ( density= 840 kg/m3) passes through a knife-edged orifice, characterized by
Cd = 0.6 at a volumetric flow rate of 2 liters per minute. If the pressure drop across the orifice is 2 kPa.what is the cross sectional area of the orifice?
a two-stage air compressor operates at steady state compressing 10 m3min of air from 100kpa 300 k to 1200 kpa. an
A piston-cylinder contains 0.1 kg of superheated steam at 180 ¯ C and 5.0 bars. The piston is frictionless and freely floating. Heat is added until the final volume is twice the initial volume.
Water flows through a long tube of circular cross section at a mass flow rate of 0.01 kg/s. The heat flux through the wall is maintained uniformly at 3000 w/m^2. The water enters the tube at 20 C. The inside diameter is 7.5cm. Find the required lengt..
what two outcomes characterize the response of an opaque surface to incident radiation? which outcome affects the
Consider a power plant operating on an ideal Rankine cycle without feed water heating. Steam enters the turbine saturated at 1000F at the rate of 5 x10 lbm/H. The turbine exhausts to a surface condenser at 1 psia. The condenser has an overall heat tr..
The crystal structure of iron is BCC at temperatures below 912°C and FCC above 912°C. Calculate the weight of one unit cell of iron (a) below 912°C; (b) above 912°C.
Calculate the specific weight of toluene at a place where the acceleration of gravity is 32.2 ft/s^2or 9.81 m/s^2. Express your answer in both lbf/ft^3 and kg/m^3. Repeat this for Mars whre the acceleration due to gravity is 37.5% of that on Earth.
water from a reservoir maintained at 20 deg c is pumped steadily along a horizontal pipe from which it is discharged
Gasoline flows from a 0.25 m diameter pipe in which the pressure is 250 kPa, that contracts into a 0.125 m diameter pipe in which the pressure is 100 kPa. If the pipes are horizontal bad viscous effects are negligible, determine the flow rate (Q). (G..
A dump truck is shown in the figure. The loaded container has a mass of 8000 Kg and may be modelled as a solid homogeneous block. The hydraulic cylinder applies a force of 300 kN to the container in the starting position shown.
for a velocity field given by v0.1xi-0.1yj where x and y are in meters and v is in ms. finda. the equation of the
the magnitude of the velocity vector of the car is v80 fts. if the vector v forms an angle theta 0.09 rad with the
