On one side of a heat exchanger, liquid water at 200 kPa and 25 °C enters at a rate of 0.63 kg/s and exits at 35 °C. Air at 250 kPa, 120 °C enters the other side of the exchanger at a rate of 0.5 kg/s. (a) Find the rate of heat transfer (kW) to the water. (b) Draw a schematic of the system. (c) Determine the air outlet temperature (°C)
Calcium oxide (CaO) is formed by decomposing limestone (pure CaCO3). In one kiln the reaction goes to 70% completion. What is the composition (by mass) of the solid product (CaO) withdrawn from the kiln? (Hint: there will be two separate product s..
Steam @ 10 MPa, 600 degrees celcius enters the first-stage turbine of an ideal Rankine cycle with reheat. The steam leaving the reheat section of the steam generator is @ 500 degrees celcius
The desire is to raise the temperature of the ambient air from 60 degree F to 350 degrees F ---- I need to calculate the amount of steam energy in BTU's per minutes and lbs of steam per minute necessary to accomplish the increase in air temperatur..
The nominal breaking strength of the rope is 10,000 lbs. Calculate how much payload this assembly can allowably pick up. Show your work.
The humidity of air can be determined by use of two different thermometers; a 'dry bulb' thermometer and a 'wet bulb' thermometer. explain how these thermometers can be used to estimate the amount of water vapour in the air.
Calculate the maximum bending stress at mid-span, and, for the same section, locate the neutral axis. Neglect the weight of the beam
Determine the analytical solution for the maximum stress of the beam shown; compare with stress results from SolidWorks.
find the total heat loss per m length of the steam line. Find also the temperature at the interface of steam and insulation.
Consider a cylindrical titanium wire 3.0 mm in diameter and 2.5 x 104 mm long. Calculate its elongation when a load of 500N is applied, assuming that the deformation is totally elastic.
what is the specific heat of air in US customary units given that its value in SI units is approximately 1 kN.m/kg.K?
