Find the expression for the ratio of the stagnation pressure after a shock wave to the static pressure before the shock wave as a function of k and the Mach number upstream of the shock wave Ma1.
Heat is to be supplied from a geothermal source at 140°C. The minimum rate of heat supply is

For turbulent flow in a circular pipe find r/r0 at the radial distance from the centerline where the mean velocity occurs
A 25-mm diamenter shaft is pulled through a cylindrical bearing. The lubricant that fills the 0.3-mm gap between the shaft and bearing is an oil having a kinematic velocity of 8.0x10^-4 m^2/s and a specific gravity of 0.91.
A hydraulic jump occurs at the entrance of this channel, with a downstream depth equal to the uniform flow depth. What is the upstream depth, y1, of the hydraulic jump?
the flow profile is such that u=u(max)*(1-(r/R)^2) where u is the flow speed and r is the distance from the centre of the pipe in the radial direction. What is the shear stress on the pipe wall What is the shear force exerted by the oil on a 1m lo..
A rod was held on point B and the telescope is inclined so that the horizontal cross line of the transit intersects the rod at the 5.2 ft mark. If the reading on the vertical limb of the transit was +25° 19',
Discuss bracing types of buildings with real-life example. Provide photograph or sketch for each type of bracing.
You are a construction engineer working on a large concrete foundation project, involving the placement of over 500,000 c.y of concrete. The construction site is adjacent to a salt-water source (bay) & it is decided to set up a concrete batch plant o..
Derive an expression for small flow rates over a spillway, in the form of a function including dimensionless quantities. Use dimensional analysis with the following parameters
At the instant when angle theta= 50 degree, the horizontal guide is given a constant upward velocity v0 = 1.3 m/s. For this instant calculate the force N exerted by the fixed circular slot and the force P exerted by the horizontal slot on the 0.60..
The probability is 1% that an electrical connector that is kept dry fails during the warranty period of a portable computer. If the connector is ever wet, the probability of a failure during the warranty period is 5%.
