In Figure 19.19, slope distance S was observed as 19,875.28 m.The orthometric elevations of points A and B were 657.73 and 1805.54 m, respectively, and the geoidal undulation at both stations was -30.5 m. The instrument and reflector heights were both set at 1.50 m. Calculate geodetic distance A'B'. (Use an average radius for the Earth of 6,371,000 m.)
Calculate the work necessary to compress air in an isolated cylinder from a volume of 6 ft^3 to a volume of 1.2 ft^3. The initial pressure and temperature are 30.0 psia and 50 degree F, respectively.
Steam flows steadily through an adiabatic turbine. Theinlet conditions are 10 MPa, 450 C and 80 m/s. and the exitconditions are 10 kPa, 92% quality at 50 m/s.
A simple beam of Douglas-Fir Larch, select grade, has a span of 18 ft with two concentrated loads of 3 kips each placed at the third points of the span. Neglecting its own weight, determine the size of the beam with the least cross-section
Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall. Rope segment BC creates an angle of
A 10-min experimental run shows that 75% of a reactant is converted to a product by a zero-order reaction rate. What would be the fraction converted in a half-hour run. Assume the reactor is a batch reactor.
It is required to dewater a construction site 80 m by 80 m. The bottom of the construction will be 1.5 m below the initial water surface elevation of 90 m. Four pumps are to be used in 0.5-m diameter wells at the four corners of the site.
Disregarding frictional losses, determine the highest rate of heat transfer to the air in the duct without affecting the inlet conditions.
It is required to reduce a pipe of diameter 8 in to a minimum diameter pipe that allows the downstream velocity not to exceed twice the upstream velocity. Determine the diameter of the pipe. Assume smooth transition
An 80 kg astronaut took his bathroom scale (a spring scale) and a beam scale (compare masses) to the moon where the local gravity is g=1.67 m/s^2. Determine how much he will weigh
A column 8.2 cm in diameter is packed with sand and water is flowing through it. The head at the upstream end is 1.98 m. Head at the other end is 1.82 m. The column is 0.80 m long. K is 4.2 x 10-4 m/s and ne is 0.080. The positive x direction is t..
