Adiffuser in a pipe flow is basically a slow expansion of the pipe diameter, which slows down the fluid velocity and increases the pressure (the bernoulli effect). water at room temperature flows with a volume flow rate of 0.0250 m3/s through a horizontal diffuser in which the pipe diameter increases gradually from d1 = 6.00 to d2 = 11.00 cm. the irreversible head loss through the diffuser is estimated to be 0.46 m. the flow is turbulent, and the kinetic energy correction factors at both the inlet and the outlet of the diffuser are assumed to be 1.05. repeat using the bernoulli equation (ignore irreversible head losses and ignore kinetic energy correction factors – in other words, set the kinetic energy correction factors to 1). calculate the percentage error in the result due to the bernoulli approximation. the percentage error in the result due to the bernoulli approximation is calculated to be

The weights of bags filled by a machine are normally distributed with a standard deviation of 0.05 kilograms and a mean that can be set by the operator. at what level should the mean weight be set if it required that only 1% of the bags weigh less than 9.5 kilograms? round the answer to 2 decimal places.
