Sketch an appropriate diagram to support your arguments. (CO2: PO2 - 6 Marks) b. In a water supply system, water flows in from pipes 1 and 2 and goes out from pipes 3 and 4 as shown in Fiqure Q2 (b). If all the pipes have the same diameter, explain the flow velocities in each pipe...
4) Consider the schematic diagram of a thermowell/thermocouple which is used to measure temperature (T) of a fluid. The measured temperature Tm is recorded via thermocouple leads. The energy balance equation is given below. T. mc = UAT-T...) dt Here, m is the mass of the fluid in the thermowell, C is the specific heat, U is the heat transfer coefficient and A is the area of the thermowell wall. Page 2 of 2 (a) Derive the transfer function between...
1. a) Describe what the Continuity equation is used to determine in hydraulic calculations. 2 marks b) Bernoulli's general energy equation considers potential energy, pressure energy and kinetic energy. What are three other possible additional types of energy that can be considered in this equation? 3 marks c) Provide the equation for Volume Flow Rate, Weight Flow Rate and Mass Flow Rate. Beside each equation, indicate the metric units for each component of the equation.
A cogeneration plant is similar to a power plant, but some of the thermal energy in the working fluid is used for process heat (for example heating buildings, steel making, or oil refining). An ideal reheat Rankine cycle with regeneration is modified to a cogeneration plant by adding a process heater as shown in the figure below. The process heater acts as a heat removal step where the enthalpy of the steam is reduced by the heat output (qprocess=h7-h3). The...

The Figure shows a shell and tube condenser where a vapor is condensing on the shell side due to heat removal by a coolant flulid whigh flows though the tubes. To analyze the steady state energy transport in this situation. We can focus on a single tube and apply the differential balance equation. Since the coolant is heated as it flows through the tube, we have both molecular and convective energy transport in the flow direction....

Problem 2 (Marks 3) AGL Energy is expanding the capacity of the Liddell Power Station. The plan is to commission a steam turbine power plant that operates on a regenerative Rankine cycle and has a net power output of 150 MW where steam enters the turbine at 10 MPa and 500°C, and the condenser at 10 kPa. The isentropic efficiency of the turbine is 80 percent, and that of the both pump is 95 percent. Steam is extracted from the...

The Magellan spacecraft (as shown in Figure 2), also referred to as the Venus Radar 5. May 4 1,035-kilogram robotic space probe launched by NASA on Mapper, was a 1989, to map the surface of Venus using Synthetic Aperture Radar and measure the planetary gravity. The position control system for the spacecraft is governed by the following equations: d2p dp +4p +2 dt2 dt =r-p de 0.602 dt 71 The variables involved are as follows: desired platform position r(t) p(t)...
The figure shows a schematic of a power plant that has two steam turbines. The water (the working fluid for the plant) leaves the high pressure turbine (HPT) as saturated vapour at 1000 [kPa]. Part of this flow is diverted to an insulated heat exchanger, which we hot airstream to create superheated steam that enters the low pressure turbine (LPT). The air mas flow rate is 19.5 k/s and the air temperature drops from 1100 to 6001 as it goes...
