It is desired to pump 600 m3 /h of liquid ammonia (ρ = 607 kg/m3 ) at a speed of 2500 rpm and a pressure rise of 1000 kPa.
(a) Determine the type of pump best suited for this duty.
(b) Using the appropriate dimensionless pump characteristic curve, find the diameter and number of stages required to meet the pumping requirements.

Gasoline (density = 680 kg/m^3 and kinematic viscosity = 4.29x10^-7 m^2/s) is transported at a rate of 150 L/s for a distance of 2 km. The surface roughness of the piping is 0.03 mm. If the head loss due to pipe friction is not to exceed 10 m, determ..
Suppose you have data such as in the Shirt Orders database. How could this data be stored in an Excel file? Would anything be lost? In general, what is the advantage of storing such data in a database package such as Access rather than in Excel?
What is the correct decimal notation for the number 1.345 x 10-1?
The data listed below are claimed for power cycles operating between hot and cold reservoirs at 1000 K and 400 K, respectively. For each case determine whether such a cycle is in keeping with the first and second laws of thermodynamics.
